I've been vibe coding some music tools and after some researching let Claude get going with imgui (https://github.com/ocornut/imgui) to build a tool I use for local authoring. It's pretty pixel-dense and looks alright to me. It runs on MacOS and Linux, which is enough for my needs now. Claude has been pretty decent at getting audio stuff going on MacOS and can even tap into various accelerators in MacOS libraries. It's had no problems loading and playing mp3s and m4as, which is the majority of my collection. I'll probably prototype an music manager off of that. It'd be great if it works out for Android as well.
