Some improvements:

It is a really nice app, but heres a few ways it could be improved: First, we need more cut lines for more precise cutting. Second, we should have the ability to change the pitch at certain points. Third, itd be pretty neat if we could use our own downloaded videos. And finally, I would like to be able to speed up the song and then slow it down, rather then being stuck with one speed. These are just some thought, and thank you for your time and effort!
