I'm assuming you hating on it aren't aware of Fall Out Boy.. It's pretty much their sound, and they have some level of popularity for younger audiences. Plus.. its Missy Elliot. anything with her is NEVER considered bad. lol
Also.. It's not a remake.. A few of the lyrics are similar... but "I'm Not Affraid" is the focus point of this song..
Sounds nothing like any FOB song I have ever heard. Not that I am a fan of their music, but it's not normally vomit inducing, like this is :)
