TL;DR: Can the currently playing track be added to a certain playlist "Driving" for example via script/program (Linux)?

I have several playlists that I want to keep up to date.
I listen to a lot of new music, and want to index several thousand tracks and sort them into these playlists:

To make the sorting process easier, I was thinking about making a program or script which listens to keyboard shortcuts and appends it to the specified playlist:
CTRL + SUPER + 1 would be "Best Tracks" for example.

Is this possible with the current command line tools? If not, what SQLite command would be appropriate for java's JDBC to insert a track into a certain playlist?
