I wish we could just "ban" a song from ever playing, that way I won't have to make a new playlist from an existing one just because i don't want to listen to these one or two songs I find super annoying.

I have playlists that work as filters for me, if I'm mass copying a playlist I first put it into the filter playlist, then I press "skip duplicates" now all the songs that are not on my shit list (fiilter list) will end up at the bottom labeled "now" on "date added" then I copy those to the playlist I want to and erase them from the filter.
