From best to worst! BEWARE!

I loved this app and used it regularly.
1. After the latest iOS upgrades it no longer can even access my music library.
2. Repeated emails to developers with NO support or response.
3. Recently purchased "Music Trainer" by same firm for $3.99. It is EXACTLY same app with new name. Thought Id get a clean and workable file. Same app with same failure. Wont work.
Go elsewhere and buy an app thats supported by developer.

Its true about Slow Down Music Player
