Use CocosDenshion. However, you may want to convert your audio files to AAC encoded *.caf format, as that is the preferred format.

#import "SimpleAudioEngine.h"

//preloading is important. do it in the scene init function
[[SimpleAudioEngine sharedEngine] preloadBackgroundMusic:@"MyBgMusic.caf"];
[[SimpleAudioEngine sharedEngine] preloadEffect:@"MyEffect.caf"];

//later on
[[SimpleAudioEngine sharedEngine] playBackgroundMusic:@"MyBgMusic.caf"];
[[SimpleAudioEngine sharedEngine] playEffect:@"MyEffect.caf"];
