Works but kidnapped my original music

It automatically kidnapped my original music I downloaded from my site.. then only gave a 30 second demo of each 😡

Works OK.

The very first thing I look for before downloading a new app is the app privacy. If it doesn’t show “Data Not Collected” then I’m much less likely to give it a serious look. Amazing Slow Downer passes the Data Privacy test so on that score it gets 10 out of 5.

I have other slow downer type apps as well but I’m looking to be able to recommend apps to my students. The difficulty I have with this app is that I don’t use Apple Music. I just do it the old fashioned way - buying individual songs. But I can’t seem to use Amazing Slow Downer with the selection of songs I have in iTunes. It seems limited to the online Apple Music and I find that puzzling.
