Okay, like I promise, here are the European batch of Elsa and their performance on the song Let It Go! So are you ready? Here we go.

Catalan (Voice Actress: Gisela)

Ok, I'm not really a fan of Catalan, well maybe because it's new and especially when it comes to Disney (or non-Disney) dubs.
Gisela has an amazing voice, so I'm going to give her a round of applause for her Catalan dubbing. (ratings: 8/10)

Italian (Voice Actress: Serena Autieri)

I really love Italian because it's such a beautiful language, Serena's portrayal of Elsa is really extraordinary perfect. She nailed the song without auto-tune!
Her voice is perfect for Elsa and I think she's the strong contender among all of the European batch! So good luck or as I said in Italian: Buona Fortuna! (ratings: 10/10)

Czech (Voice Actress: Monika Absolonova)

The first Slavic dub that I really enjoy listening, her voice is very superb and her rendition is amazing! She's another strong contender for the European batch and I strongly salute her for that.
Unlike Idina Menzel, she's not pitchy and her voice is smooth and at the same time, relax. (ratings: 10/10)

French (Voice Actress: Anais Delva)

French is another beautiful language, Anais is very young and this is the kind of actress that I'm very happy with because Elsa is young and Anais is also very young!
She nailed the song and I really should say Viva La France! So congratulations to Anais on her portrayal of Elsa. (ratings: 10/10)

Dutch (Voice Actress: Willemijn Verkaik)

Her singing is perfect and when she sang the first verse, she sounds very ominous and as the chorus arrive. She gradually comes out from being ominous to being powerful, she is like saying 'I'm Elsa and I want to Let it Go!' that kind of feeling.
Just so you know that Willemijn also did the German dub, to which I'm going to cover on later on! (ratings: 9/10)

Castillian Spanish (Voice Actress: Gisela)

Once again, Gisela also did her Castillian Spanish dub and I personally think she sounds even better than her Catalan dub. She projected herself more and is more lively and gentle with her singing!
The European Spanish is gentle and sweet, especially with Disney songs as I listen to Il Divo's songs whenever they sing a song in Spanish! So congratulations Gisela (ratings: 9.5/10)

Slovakian (Voice Actress: Andrea Somorovska)

For the Slovakian dub, I have very a similar opinion as her Czech dub. But I guess she also sounds relatively young and I am very surprise that Europe has very good singers!
I feel happy for them and especially for Andrea, I would like to wish her good luck on her musical journey ahead! (ratings: 10/10)

Hungarian (Voice Actress: Nikolett Furedi)

Now, Hungary has a lot of good singers especially. I had seen Nikolett's country girl, Kata Janza providing the singing voice of Princess Jasmine in the Hungarian dub of Disney's Aladdin. So, my opinion on Nikolett's rendition is beyond average, but on the other hand, perfect!
I love the Hungarian language because it sounds unique, but one problem is the lyrics. I heard that it doesn't really fit Elsa's personality very well, but Nikolett's performance is astounding at the same time. (ratings:9/10)

German (Voice Actress: Willemijn Verkaik)

As I promise, here is Willemijn's German dub. Her German rendition is so-so. But on the other hand, she sounds wonderful and perfect. (ratings:7/10)

Romanian (Voice Actress: Dalma Kovacs)

Now we heard about her from Eurovision, and her performance on the Romanian dub is really cheerful and yet at the same time, mischievous!
She convinces everybody that Elsa is being cheerful in her song and I'm very happy for the Romanians because they also got great singers. (ratings:10/10)

Greek (Voice Actress: Sia Koskina)

Like her Romanian counterpart, she also sounds cheerful and yet energetic with her singing! The Greeks are really amazing and yet extraordinary when it comes to Disney dubs.
So, I must congratulate them and for selecting Sia to sing Elsa! (ratings:9.5/10)

Lithuanian (Voice Actress: Girmante Vaitkute)

Another amazing singer, she's also a relatively new singer, and she did a lot of singing with the likes of Adele, Alicia Keys and Whitney Houston. I should give her a round of applause she also nail Elsa astoundingly perfect!
I grew a liking on her obviously and she's perfect! (ratings:10/10)

Flemish (Voice Actress: Elke Buyle)

I think that she sounds relax than Dutch because they sound awesome, Elke is another contender for the role of Elsa. In fact, her name is also quite similar to Elsa's! (ratings: 9.5/10)

Danish (Voice Actress: Maria Lucia Rosenberg)

An amazing singer from Scandinavia and she sounds very energetic, she also has a rock & roll voice quality in her. It's like Elsa has turn into a bad girl all of a sudden and she's like from a Queen to the bad girl princess that we all wanted to be! (ratings:10/10)

Estonian (Voice Actress: Hanna-Liina Vosa)

She also sounds young and like her Romanian counterpart, she sounds hippy and dashing. She is also trying her best with her singing and I truly appreciate that! (ratings:8/10)

Swedish (Voice Actress: Annika Herlitz)

Okay, as you know that in the video, she landed No. 1, and I have to agree! She nail the song with everything ranging from emotions to progress!
I think Sweetie-94 will be very proud because I think that Annika is going to score a perfect ten for her performance! (ratings:10/10)

Finnish (Voice Actress: Katja Sirkia)

Her voice is quite bouncy and yet youthful, I love how her voice flows with the song. (ratings:7.5/10)

Icelandic (Voice Actress: Agusta Eva Erlendsdottir)

This is the voice that I was looking for, the perfect voice for Elsa. In fact, she also did the voice of Rapunzel in the Icelandic dub of Disney's Tangled. So I wouldn't be surprise at all!
Overall, I think she nailed it! So congrats Iceland. (ratings:9.5/10)

Bulgarian (Voice Actress: Nadezhda Panayotova)

Another transition from Rapunzel to Elsa, her performance as the latter is amazing because she's coming out from being the shy and innocent Rapunzel to the energetic Elsa. (ratings:10/10)

Latvian (Voice Actress: Jolanta Strikaite)

The last singer that I'm writing about from the Baltics, there's something unique about her, especially about her performance in this song. The chorus is really gentle compare to her Finnish counterpart, she's not out of tune and she sounds very young and very Elsa! (ratings:9/10)

Norwegian (Voice Actress: Lisa Stokke)

Elsa's and Anna's native mother tongue, she sounds perfect and wonderful for Elsa. As I listen with my eyes close, it's sounds like Elsa is telling us to let it go in her native language (ratings:9.5/10)

Serbian (Voice Actress: Jelena Gavrilovic)

As I saw her singing in the behind the mic, she projects her voice very well and I was blown away by her performance! (ratings:10/10)

Russian (Voice Actress: Anna Buturlina)

I love Russian and when I listen to this version, it sounds like the Snow Queen from the original 1957 story is singing this song! But one thing is that her performance is extraordinary and yet interesting. (ratings:8/10)

Croatian (Voice Actress: Nataša Mirković)

The second last one from the Balkans, her performance is so-so. But I have to say she's improves during the second half of the song. (ratings:8.5/10)

Ukrainian (Voice Actress: Shanis)

Whenever I listen to the Ukrainian version, I feel relax, in fact she's a jazz singer and at the same time Elsa sounds youthful and very soulful. (ratings:8/10)

Portuguese (Voice Actress: Ana Margarida Encarnação)

I love her body gesture during the Behind the Mic, unlike her European counterparts whom they are all very stiff. She's animated! (ratings:10/10)

Slovenian (Voice Actress: Nuška Drašček Rojko)

The operatic Elsa! For once, Elsa has a class lesson with the likes of Sarah Brightman and Katherine Jenkins. Although at some parts, it's pitchy but good try overall. (ratings:10/10)

Turkish (Voice Actress: Begüm Günceler)

I love Turkish music and their voices, they sound very exotic, the same with Elsa! She sounds very exotic with her voice, which sounds very sultry and smooth! (ratings:9.5/10)

Albanian (Voice Actress: Antonela Çekixhi)

This has gotta to be the WORSE performance out of the European team! It sounds like a karaoke party going on and that she's like very tipsy while singing. I also hope she's not going to voice anymore Disney movies! (ratings:0/10)

Polish (Voice Actress: Katarzyna Łaska)

Finally, the last European batch that I'm going to write about. She sounds fresh and young. I am totally very happy for the Polish dub. (ratings:10/10)

Conclusion

Wow, this list is the longest that I had ever done! But overall, these are my thoughts on their performance. I'm quite surprise that they're all good!
