Notice - July 21st, 2026
Due to changes to how YouTube Music loads its own scripts, this userscript now causes visual bugs and may also cause certain things to break. While I am looking into a solution to fix this, it's possible any workaround will require a substantial rewrite of the logic behind this script and may go beyond the scope of this project.
