Good sound quality but missing key features

Good sound quality but not enough practical features. As an instructor I would like a playlist that a - could have individual tempo changes to different songs in a playlist (example - first 2 128 bpm for warm up, move to higher for the body & have cool down back to 90-100); b - have ability to save multiple adjusted playlists for later.

The current set up makes it useless to set it & forget it for classes. I was disappointed with what it was missing for the cost of the app.
