Nice, just one problem

Whenever I try to fast forward to a certain part, it won’t let me. Otherwise nice app!

Pretty Good

This app is pretty good! But there’s a little bug. At the “playlists” part, there’s a thing at the bottom that says, “how to keep playlists?” I clicked it, and everything was Japanese, and it wanted me to signup for something and I didn’t even know what it was. Please fix this.
