Hehe...speaking of which, we just got zero-bombed! It's actually kinda fun to watch how the ratings go. Part of me imagines that there's someone who clicks on a song, goes, "This isn't Metallica!" and instantly pushes zero after 10 seconds of listening...
Which is exactly what happens in the real world of radio-play. Anyone can sign up to be a tester for radio stations. They get sent tracks which they are to vote on. People almost always vote 5, or 0. Those who vote 5 usually do so within 15 seconds. Those who vote zero usually do so within 5 seconds. If a song doesn't get a 3.5 star rating, it doesn't get on the air.
And that's how internet trolls make sure that everything on the radio sounds exactly like everything else. Nowadays, Bohemian Rhapsody wouldn't stand a chance.
