Okay, instead of #coding on #MSXplayRipper, I ended up doing some more #ScratchYourOwnItches by creating 2 fairly simple #Bash #CLI scripts to help me track and re-open the media I've launched from the command-line: https://github.com/FiXato/cli_player_queue

#CliPlayerQueue basically wraps around #mpv, gets the page title, tracks it in a history file, and launched mpv.
Afterwards I can browse the history file with the same command, or immediately filter it by title or URL.

The title retrieval is very simple, and basically only works for YouTube and plain HTML pages atm, but f.e. Twitch support will be added soon.
(There are probably pre-built solutions out there too, but I like #ReinventingTheWheel...)

Put on some #MGS / #MGSDRV / #MGSEL #chiptune files via #WinAmp because that's the only #MediaPlayer that seems to support this #MSX audio format, plugged some headphones in, and getting ready to do a bit of related #coding on my #MSXplayRipper #PetProject. :)
