If you read the fine print, the next significant release will be written in Common Lisp but the current releases are written in Crystal.

It's a Common Lisp program for end users and I can literally use it in 3 clicks, thanks to its AppImage (for Linux x86-64). Good (and rare) stuff!

It's also impressive to see that the audio decoding is mostly done in CL, without bindings.

Nice, last time I used this it was actually written in Crystal. I used it at the time to render VGM files, very handy and fast. Author is nice and responsive as well, I reported an odd issue with a VGM I had and she responded quickly.

It seems the developer has no plans to support MPEG-4 audio files.

cmus is also very cool, it’s a TUI. Paging through tracks in cmus blows iTunes out of the water.

when you have a thirst but only common lisp can quench it
