Its works great app

This is good fun with friends if you can play it over speakers. There's a list of songs with back-masking at Wikipedia. The only thing I might add is a speed control but it's fine without it. Don't buy it if you're expecting it to somehow change your life. It's just kicks and giggles. Show more

Funniest app I've ever had.

On the rare chance that this app would actually reverse the song you have absolutely no control past that - no fast forwarding, stopping, playing again, no rewinding, nothing. I wouldn't suggest buying this app, unfortunately. Show more

Super awesome but u need to make it to where you can do it with podcasts too

I am so furious that I bought this app. It won't work. When I click the song I want, it won't play!!!!!! HELP

It's really cool! Doing music and voice, pluss I got it when it was free! This is def worth 3.99...

This app works perfectly, but maybe needs more settings.

Simple and it works. Beautiful.
