I finally got around to trying this branch, but I'm afraid I can't get it to 
work. I'm able to evaluate your `emms-actions-add` examples (with point at the 
target track), but when the song comes up in the playlist, nothing happens. I 
also tried different functions, like just printing a message to the echo area, 
and nothing seemed to execute then either.

I'm using the mpv backend if that helps you reproduce the issue. Thanks for 
working on this, and sorry it took me so long to respond!
