woob

I really love it a whole ton for so many reasons. It's the one thing that really got music making to kinda click with me. Plus you can share an entire song with just a single URL and embed it in any webpage, which I used for this page https://woob.neocities.org/music.html

The "whole song in URL" thing also means it's really really easy to collaborate because you can just bounce the URL back and forth with each iteration
