"We are excited to offer Amazon MP3 customers DRM-free MP3s from SONY BMG, which represents many of the most popular musicians from the past and present. Our Amazon MP3 customers will be able to choose from a full selection of DRM-free music downloads from all four major labels and over 33,000 independents that they can play on virtually any music-capable device."
We never thought this day would come. However, with Warner Music moving to an MP3 format, Sony had little choice, as if 3 out of 4 music labels were DRM-free, and Sony was the lone holdout, you can see how much sense that would make. But this is a major coup, and you can bet Apple isn't happy.
