convert MPMediaItemCollection into the Nsdata

Question

I had imported an .mp3 file form MPMediaPickerController by below code:-

MPMediaPickerController *mediaPicker = [[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeAny];

    mediaPicker.delegate = self;
    mediaPicker.allowsPickingMultipleItems = YES;
    mediaPicker.prompt = @"Select songs to play";

    [self presentModalViewController:mediaPicker animated:YES];
    [mediaPicker release];

Now i want to Convert the selected .mp3 file into NSDATA so that i can upload that nsdata into the server :-

- (void) mediaPicker: (MPMediaPickerController *) mediaPicker didPickMediaItems: (MPMediaItemCollection *) mediaItemCollection
{

    MPMusicPlayerController *musicPlayer = [MPMusicPlayerController iPodMusicPlayer];
    [musicPlayer setQueueWithItemCollection: mediaItemCollection];

    NSLog(@"==>%@",musicPlayer);
    [musicPlayer play];
    [self dismissModalViewControllerAnimated: YES];
}

The main problem in how do i convert musicfile into the NSDATA or into anyother format through which i can upload it into the server.Can then can easily use that after downloading the same file as audio file

you can use this to convert .mp3 or any media file to convert into nsdata :-

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

NSURL *soundFileURL = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/memo.m4a", documentsDirectory]];;
NSData *myData = [NSData dataWithContentsOfURL:soundFileURL];

return myData;

convert MPMediaItemCollection into the Nsdata
