Dear Microsoft Xbox 360 Team,
Previously I could only play MP3 and WMA format audio files on my XBox 360. This was very frustrating to me since I switched several years ago to encoding new tracks in AAC format (it gives better quality at lower bitrates than MP3). The end result was that I preferred to listen to music while sitting at my computer instead of while sitting on my couch.
Then you released the "new xbox experience" and provided an "optional media update" which added support for a host of additional audio and video formats (including AAC!). I was pleased. You didn't yet allow me to play DRM'd songs from the iTunes Music Store, but that was understandable because Apple was refusing to license Fairplay to anyone. Still, I was content.
Then Apple starting selling songs without DRM. Now, I could play these songs with your own Windows Media Player, but my Xbox would not play them. I was no longer content. It was pointed out that this may because Apple writes the headers a little differently for purchased vs. non-purchased songs. But the fact that the Xbox cannot handle this small difference is rather remarkable.
I am sure you all know how to fix this. So, please... just do it already.
