Wont access Apple Music – Learn That Song (REMIX Edition) — Slow down music, change the key, and loop [previously iLift] Review

I subscribe to the full boat Apple Music. Don’t carry much music on my phone and generally stream my library (think that happened originally when I did iTunes Match). So I downloaded hotel California and gave this app access to my music as I saw instructed in other reviews. When I try to access the downloaded song via the app I get an file protected error. This is a track that I had purchased from Apple Music prior to iTunes Match and now the Apple Music full subscription. The way Apple Music protects its contents if you are a streaming customer with available downloads is not compatible with this app from my experience. Think if you are someone with a lot of mp3s that you have not allowed to get sucked up into the Apple Music vacuum of protected content which is too complicated for me to understand it might work for you. Unfortunately I have indeed been sucked (or suckered!) in already so I don’t think it will work for me.
