title: Is it possible to use NSNotificationCenter in the background for a Music Player app?
body: <p>I was wondering if it's possible to run an observer from NSNotificationCenter while the app is in a suspended state, if the selector is required to play music. Basically, it runs at the end of the song to reset the queue. Is it possible to have the selector activate, even if the app is in the background state? I know this seems like a duplicate of <a href="https://stackoverflow.com/questions/10890835/nsnotificationcenter-for-app-in-suspended-state">this</a> question, however, since my app is a Music Player, is this part of the exception?</p>
