The Jonas Brothers sing it WAYYY better. I don't like the Veronicas's version of the song. :-/ The people that like this version better are obviously BIASED.
I'm not a fan of the song but I guess it's not a bad cover. They could have picked a better song than this. I know they are really good friends with them but why this song?
I'd like to say here that even though I'm a huge Veronicas fan and a huge Jonas Sisters hater, I must admit that Burnin' Up isn't a too bad song. It didn't deserve the success it got, but at least it was bearable, unlike the rest of their songs. So, I'm not just liking it because it's the Veronicas, because there are some songs of theirs I don't like as well. I honestly believe they did a better version of Burnin' Up than Jonas Sisters.
