Okay, so I'm thinking of listening to some older rock, and I thought I should start with the Ramones..

well i's The Ramones so anything from them will be good. Are you more interested in punk?

If your more interested in punk rock then yea I say go for it!
They're awesome:) I recommend Blitzkrieg Bop, Bonzo Goes to Bitburg, I wanna be your boyfriend, Beat on the Brat,
