The tweak can be found on my repo, http://jonlu.ca/repo/
This is a fairly straightforward tweak - it replaces the "Connect" tab with "Playlists" as well as changes a few statusbar actions in nowplaying, and changes the behavior of the app when you have an Apple Music subscription.
I'd recommend to only install this if you have an Apple Music subscription. I have not tested it on devices other than iPhone 6, 8.4.
Let me know how it works for you guys!
