I put the current lyric above my windows. Forgetting the words now takes effort.

I built Spotify Lyrics for Island on macOS. The plugin reads playback from Spotify Desktop through Automation and gets synchronized lyrics from LRCLIB.

The compact pill shows a line. The expanded view shows more of the track and its lyrics. Spotify supplies playback state; the plugin follows along.
The source is MIT licensed. It needs Spotify Desktop and a compatible Island host.
