Amazon has a $5 sale on lots of good albums. Everyone should be comparing iTunes prices to Amazon's mp3 prices before buying.
Here are my picks
Birth Of The Cool (Rudy Van Gelder Edition) by Miles Davis. This is an amazing album. Everyone should listen to it!
Young Americans by David Bowie.
Oh, Inverted World by The Shins.
Lust For Life by Iggy Pop.
