Some disappointment yet some GREAT equalizing

Mixed review. Spent the $0.99 but bottom add remains and I then discovered most songs won't import for some reason. Nonetheless on song equalizing, the multiple frequency range adjustments work VERY well. Now if this thing could stream my MP3 files from Box, THAT would be fantastic.

As a non-professional avid transponser, I have bought so many songs on Apple Music for this app. I absolutely LOVE how easy it is to navigate, how transposing works, how simple adding songs into the queue is, etc. Only issue is not being able to pause from outside of the app, but that isn’t a huge deal! I love being able to show my friends the power of transposing music ❤️

O K?a ,

Doesn’t work!

After pushing every button on this thing, I cannot get anything to play! ( And yes all my music is downloaded ) When I go into settings and push, developer support… A blank page comes up with a caption at the top saying “loop session” As is, it is absolutely useless to me!
