I've been working on a rock version of "Smile Song", but I'm not quite sure it is ready for prime time yet, and I could use some feedback.
It took me quite a while to come up with an arrangement that I liked, and also to find a good isolated vocal track (thanks MrMusicalPony on YouTube!). But then the track had no backing vocals and no choir at the end. So I used some DAW magic to recreate the backing vocal track, and used the original MLP recording for the choir part at the end. Some of the original instrumentation bleeds through, but I did my best to cover it up.
Anyway, I could use some input on whether the track is good as is or needs more work.

Thanks,
One Trick Pony
