Buying music from the iTunes Store has taken a turn for the better. First, all songs will be DRM-free. Existing libraries can be upgraded for 30¢ per song. The music files will still be in Apple’s AAC format but can be converted to MP3 by right-clicking on the song in iTunes. Second, there’s a new pricing system, with three price points: 69¢, 99¢, and $1.29. I’m assuming that popular new releases will be the highest, while older, library songs will be the lowest. The majority of songs are DRM-free right now, with the remainder switching over by the end of March. The new pricing scheme will take effect in April.
