Sony will be selling DRM-free tracks through Amazon. Hopefully this means they’ll drop that stupid trading card scheme.
Now that Amazon will sell DRM-free tracks from all major labels, that leaves iTunes as the only significant store still selling DRM-crippled music. I’ve bought a lot less music in iTunes over the last year for that reason. When I want to buy an album, I always check eMusic first, and if it isn’t available I’ll then try Amazon. I’d only buy it in iTunes as a last resort, if I can’t find it elsewhere.
