/r/MarvisApp. Pro mode for Apple Music. Customize metadata in lists (playlist, album list) and mini player/full screen player; also, smart rules to whittle down lists. So basically what you do is, you make a section for all the songs in your library (boring) and then you use rules to make a smart playlist that changes dynamically.

$8 USD, one time fee (also has a $5 Last.fm add-on, but I don't need/use it).
