I thought about surrealistic pillow by jeffersons airplane. The problem is I just don't know what album to buy from them, or from Tull, or Lynyrd Skynyrd. You can listen to 30seconds of each track on iTunes, and you can buy single tracks, but the trouble is if you end up buying loads of tracks it eventually becomes cheaper to just buy the whole album, only then I THINK its too late. Anyways I zapped Stand Up the second Tull record, Electric Ladyland by Hendrix was on there for 5 quid and some belle and sebastian tracks. Oh yeah and that one called Atlas by Battles. As for Zeppelin and Aerosmith, well I already own most of their stuff on CD.
