Question

I need to start playing a song (which is in the iPod library) in another iOS App using the name of the song.

I’ve studied some of the MediaPlayer framework, but didn’t find anything useful.
I know this can be done, as a couple of apps in the App Store do it, such as SoundHound, which lets you play a certain song you’ve discovered if you have it in your iPod library.

try this :

EDIT:

you can try this to reach songs:

#pragma mark - Media Picker

- (IBAction)showMediaPicker:(id)sender
{
    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];
}

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

        [musicPlayer setQueueWithItemCollection: mediaItemCollection];
        [musicPlayer play];
    }

    [self dismissModalViewControllerAnimated: YES];
}


- (void) mediaPickerDidCancel: (MPMediaPickerController *) mediaPicker 
{
    [self dismissModalViewControllerAnimated: YES];
}
