Amazon sells digital music - challenges iTunes

I like this service - Amazon's new MP3 service uses 256kb VBR files with NO DRM. I think it will be very popular. Link Because it will work on both iPods and Windows Media based players, I think it will draw a lot of interest. Currently they only have 2 of the 4 big labels, but I'm sure the other 2 will be added, as it is only good for them to have competition in the online retail channel.
