Amazon MP3 store is good.
When I heard Amazon was launching a re-launching a music store, I thought it would suck, like unbox and all the other digital media download stores Amazon has ever made.
But it doesn't suck. It's totally awesome.
you get normal DRM-free MP3 files for only $0.99 (sometimes $0.89).
Albums seem to be $7 - $9.
They have a download manager for Mac. It's actually a really nice, simple, clean piece of software.
Hopefully this will trigger a price war with iTunes and we'll see music prices drop to what they should be. I think that means $0.05-0.10 for crappy songs and $0.50 for popular/good tracks. Albums should be $5.
