Basically rate the song above, use anything you want to rate it. Good, bad, 10/10, 1/10, I don't care as long as people know what your trying to say about the song. You can also critic it if you like. Two things before we start though...
-Don't say things like "I can't believe you listen to this crap", saying "I didn't like it" or "it was bad in my opinion" will do fine, everyone has opinions, that doesn't mean you get to be annoying about it
unless it's Justin Bieber. =P
-If someone does do that just try to ignore them and be un-bias towards theirs songs, be the bigger person.
Here we go.
