    //NSMutableDictionary *musicList = [NSMutableDictionary dictionary]; 

    MPMediaQuery *query = [[MPMediaQuery alloc] init];
    [query addFilterPredicate:[MPMediaPropertyPredicate
                               predicateWithValue:[NSNumber numberWithInteger:(MPMediaTypeMusic)]
                               forProperty:MPMediaItemPropertyMediaType]];

    for (MPMediaItem* item in [query items]) { 
        [appDeleg.arryMusic addObject:item];
    }

    NSLog(@"Count :: %d ",[appDeleg.arryMusic count]);
    [query release];

//      MPMediaItem *song = [appDeleg.arryMusic objectAtIndex:indexPath.row];

    NSURL *aURL = [appDeleg.arryMusic objectAtIndex:indexPath.row];
    //[song valueForProperty:MPMediaItemPropertyAssetURL];
    [[self avPlayer] replaceCurrentItemWithPlayerItem:
     [AVPlayerItem playerItemWithURL:aURL]];
    [avPlayer play];
}

but my sound file not going to play...

Hey any one know about this than help me..

You are not storing a URL in your array, you are storing instances of MPMediaItem

What you need to do is extract the assets url from the media item. You can do this as follows ...

MPMediaItem *item = [appDeleg.arryMusic objectAtIndex:indexPath.row];
NSURL *url = [item valueForProperty:MPMediaItemPropertyAssetURL];
[[self avPlayer] replaceCurrentItemWithPlayerItem:[AVPlayerItem playerItemWithURL:url]];
[self.avPlayer play];
