A few ideas
On the search, add the functionality to search by instrumentation. I use this to search for music I can play on specific instruments, and on this app, its not the easiest to do. As a paying customer, this would be a nice feature to include with an update to this version. I really enjoy the major overhaul this app received about a month ago and this is my only major complaint. There is a minor glitch, if you are loading the app and playing music, if you make the music keep playing, even after you close it, the in-app audio wont work without completely closing out of the app and opening it again
