Best MP3 Download Service?

Just wondering what you guys use to buy and download MP3’s?

I want a good music service that will let me download and put the music files on my computer and my phone so I can play them wherever I want.

1 Amazon Music Store (integrated with Banshee & Amarok 2.5)
2 Ubuntu One Store ( needs a ubuntu one account)
3 Jamendo (Banshee, Rhythmbox, Amarok)
4 Magnatune (Amarok, Rhythmbox, Banshee)

All are DRM free.

Great, I was thinking Amazon might be a good place to start.

Any thoughts on Rhapsody?

Wow, just checked out Google Music. Their prices are 2 or 3 times higher than Amazon. Crazy.

Oh, maybe not. I think I was looking at multiple album sets. Still, I think I like Amazon better.
