I don't like this. Youtube videos, especially those for huge artists, are known to be hugely inflated because of bots and hacks to make it seem like they're bigger singles than they are. Plus, there's no effort being made in terms of actually using money to buy the track. There's no real benefit to it.
Plus an amusing film clip might be the reason it goes no1
Or just a ridiculous mockery song that ppl watch to laugh at like Rebecca Black will be no1
