Play music on YouTube via browser automation with playwright-cli. Use when the user wants to: (1) play a specific song (e.g. 'play Money Money Money by ABBA') (2) play songs by an artist as a playlist or mix (e.g. 'play Jay Chou's songs') (3) play genre or mood-based music (e.g. 'play relaxing spa music', 'play 60s Chinese oldies') (4) control playback — next, pause, resume, stop, skip ad, change song, close the player. Also handles song/artist name corrections from voice transcription errors.
