Yt-Music skip heard

유튜브 뮤직에서 2시간 내에 들었던 노래를 자동으로 플레이리스트에서 삭제합니다.

To avoid replaying songs you've heard on YouTube Music, songs you've heard within 2 hours are automatically deleted if they're in the playlist.
If you want to listen to the song you have listened to again, you can listen to it without deleting it by clicking "Play to the next song" or "Play".

This script is executed whenever the song being played changes.

Also, do not do anything when a song is deleted from the playlist.
It may be a little slower while being deleted.
