I don't understand why they took Xbox Music out of the core OS and made it an app.
By making it an app, doesn't that mean that it will always be slower than a core system application?
The argument for making it an app was we'd get more updates, etc. but honestly, we only needed like 5-8 more updates for the core OS player and then it would have been perfectly fine and wouldn't need any more updates. This isn't rocket science. Put in a scrubber, throw gapless playback in there, maybe make the heart button mean something, etc. and then you'd be done and could put resources on other things.
