Read the class reference

MPMusicPlayerController: http://developer.apple.com/iphone/library/documentation/mediaplayer/reference/MPMusicPlayerController_ClassReference/Reference/Reference.html

You use an MPMusicPlayerController object, or music player, to play media items from the iPod library.

AVAudioPlayer: http://developer.apple.com/iphone/library/documentation/AVFoundation/Reference/AVAudioPlayerClassReference/Reference/Reference.html

An instance of the AVAudioPlayer class, called an audio player, provides playback of audio data from a file or memory.

Apple recommends that you use this class for audio playback unless you are playing audio captured from a network stream or require very low I/O latency.
