Learn "What Is And What Should Never Be", "Ramble On", and "The Lemon Song" (all by Led Zeppelin, by the way) and you'll be able to play anything you choose for the rest of your life.
Probably an original song my band had. I had to practice a lot to play all those eight note "broken arpeggios" (or whatever you're supposed call them) in 200 bpm cleanly.
