This solution might help someone looking to launch default Music Player:

if(android.os.Build.VERSION.SDK_INT>=15){        
    Intent intent=Intent.makeMainSelectorActivity(Intent.ACTION_MAIN,
    Intent.CATEGORY_APP_MUSIC);
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//Min SDK 15
    startActivity(intent);
}else{
    Intent intent = new Intent("android.intent.action.MUSIC_PLAYER");//Min SDK 8
    startActivity(intent);
}

Used below code :

Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, "1");   
Intent it = new Intent(Intent.ACTION_VIEW, uri);   
startActivity(it);

or

Intent intent = new Intent("android.intent.action.MUSIC_PLAYER");
startActivity(intent);

Ans also prefer url :

Launching the default music player
