Amazon.com are now offering DRM free MP3 Downloads, you can buy a single track or whole albums and prices range from $0.99 per track and from $5.99 per album. This is really great to see and I really hope Apple feels the pressure from the competition.
Meh! As Stuart's pointed out in the comments the service requires a US Billing address. Still I've no doubt this will be come available elsewhere in the future - Afterall iTunes started out that way.
