Well, one record label took the bait, and Apple is following through with their end of the deal. In May, all iTunes Store songs published by EMI will be available without DRM. More specifically, these songs are 256K AAC (double the bitrate as before) and sell for $1.29 ($0.30 more expensive), and have no DRM.
The existing 128K AAC DRM-protected songs are still available for $0.99. Customers who have already purchased EMI songs may upgrade them to the new format (256K, no-DRM) and only pay the difference in price ($0.30).
