Pretty good – Learn That Song (REMIX Edition) — Slow down music, change the key, and loop [previously iLift] Review

It's a pretty good app and it's worth the price but I don't know how to delete a song that I made and I don't know how to save it and there are no instructions or anything and I have no idea what I'm doing so if you could change that it would be a great help
