Spotify - have you tried it? I've been dredging my memory banks for old teenage albums. The first Supertramp one, now Babe Ruth! Anybody remember them? It's all there! Free - well with odd adverts but between tracks... Go Try.
Also free music to learn. I was looking about for some classical guitar music and stumbled across some sites I'd recommend if you want to learn some classical stuff.
Amazing this internet thingy isn't it... :-)
