is it possible to use MPMusicPlayerController with simpleAudio Engine simultaneously in cocos2d

I have a application which have a music selection layer- an option for selecting background mp3 music reside in resource folder and an option for selecting music from ipod. Now problem is that when i select music from ipod and then after game over if i start a new game and select background music from resource music it does not start.it gives the following log message-

2011-01-08 22:45:10.085 TapTapBugs[2247:307] Denshion::CDLongAudioSource - Loading new audio source backGroundMus开发者_C百科ic1.mp3

2011-01-08 22:45:10.360 TapTapBugs[2247:307] Denshion::CDAudioManager - preload background music aborted because audio is not exclusive

22:45:10.416 TapTapBugs[2247:307] Denshion::CDAudioManager - play bgm aborted because audio is not exclusive or sound is muted

Now my question- is it possible to use - MPMusicPlayerController with simpleAudio Engine in same application or not.And if possible how to do it??
