Thanks for the help. I can indeed send to active playlist, but active playlist only means whichever playlist I'm looking at - not necessarily the one which is playing. I get search results and so on in my playlist window, so I'm often looking at a playlist which is not playing.
I already checked out foo_utils and while it has a lot of functionality for sending stuff to playlists, it will only send to specific playlists. Like you can send stuff to your "party music" playlist. The problem is that's not useful as a hotkey.
The other component there is outdated
I'm gonna register on hydrogenaudio forums and complain
