It depends on your phone and the default music player it uses. Different phones have different versions and even completely different music players. You can create an intent:
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
File musicFile = new File(SONG_URI);
intent.setDataAndType(Uri.fromFile(musicFile), "audio/*");
startActivity(intent);
and see whether the song will open with the stock music player.
