Yes. I needed access to the "next" and "previous" actions, which I didn't find in premade audio players or Tasker plugins. So I have to make my own audio player, which I can do with DroidScript. What I wanted was to upvalue a song by replaying it (causing it to be chosen in the playlist more often) and devalue one by skipping it. Which means I also need my own playlist function.

Unfortunately I still don't have access to the ID3 info, but I got around most of that already by structuring my directories by Artist/Album/Track
