iPhone - MPMusicPlayerController - Is there any limit on number of songs to select

I created my own music player that runs o开发者_如何学运维n iPhone using the class MPMusicPlayerController. I'm using the class MPMediaPickerController to select the songs and add to my player. I've around 900 songs in my iPhone. When I'm adding songs by selecting "Add All Songs" from MpMediaPickerController, the app is crashing.

Can some one tell me whether is there any solution to stop this crash?

Or is there any limit on number of songs selection that I've to impose so that app won't crash?

No, there is no limit on selection of songs.
