This is really what I was looking for as it allows me to make playlists on the go based on my own tags across my library. Nevertheless, since I already have smart playlists set in iTunes that effectively work as rule based filters (all songs categorized by genre, mood, energy, among others), I would like to see a ‘Match All’ sort of conditional for when you are including sources (instead of resulting in a playlist that adds all songs from those sources it would just add the songs featured in all of those selected sources). This would save up a ton of time, because that way I can just check a couple of my predefined ‘rules’ playlists showing up as sources, instead of manually having to add and type in the rules each time I want to make a new playlist.
