Ratings are amazing. Bad song? Jusz rate it with 1 or 2 stars and you’ll never hear of it again!
Good song? 4 stars. Very good song you want to listen each day? 5 stars. Could be a good song? 4 stars. OK song 3 -> stars. 3 stars are like radio songs. You don’t really like them, you wouldn’t play them by yourself but it’s ok if they play in the background.
