Would be great if it could somehow drag & drop, or have a hack to load the currently selected track in another app such as Traktor. I know this is a weird feature to ask, but I'm looking for something keyboard based to efficiently organize & tag my collection for DJing. Simply bring down a terminal window and select the next song.

For tagging and organizing you should definitely check out "beets": http://beets.io

I use Resonic for that, really fast, not terminal based, but pretty good with waveform support. You can move tracks by drag&drop to folders.
