I may not use this but I just had a pleasant five minutes reading through some of the source code. Off topic, but: I currently think Swift is the most interesting non-Lisp language. I tried Rust and didn’t particularly like it and I have given up using Haskell on anything but small fun projects.

Great to see useful open source projects. I now pay for YouTube Music but I still have an enormous library of MP3 music files that I have purchased over the years so I probably will build and run this player, at least for a few days.
