Sometimes the audio and visuals get off-set by a little so I'd recommend hitting the green flag a few times. Having the tab running but not actually being on it also seems to make it be more off-set. It still might get off-set regardless of what you do, but it isn't too bad.
My top 50 songs of all time (as of September 2025), every clip is clean (also every one is exactly 15 seconds long). I put a lil' Fake Fat Brighty that goes along with each song, too. This list may or may not be excluding a certain Nirvana song with too graphic lyrics (iykyk).
