Of course. Unless you're one of those people who use the Billboard Top 100 to decide what songs you like, how else would you find out which songs you like more? Get a game with mindless hack'n'slash, grinding, or collectible finding going, put all the songs in a playlist, make sure each of their ratings is set to unrated, then set up a hotkey to rate a song as 5 if you want to keep it (or 1 if you expect to like more songs than dislike) and hit play. If you have a mouse or keyboard with extra buttons, bind them to "Next" and "Rate: 5 (or 1)" to cut down on time.
