if you're actually curious how, it's because Spotify (and a lot of other really popular programs like Discord) use an Electron client to operate, which is a wrapper for a series of Chromium clients! Electron is garbage
the reason it happened when your chromebook was running slow is because Spotify requires two or three Chromium clients just to run, so it's really inefficient!
nice (also, there's a series on a dude making an os, it might help you with turning yours into an actual system)
Thanks!!! (also you just reminded me to finish it lol)
