No he just wasn't singing correctly irrelevant to it being a cover, he just isn't singing in correctly in tune. It may be very subtle but to be condescending one can obviously tell you are not ear trained.
Grow up? hahaha None of what I'm saying is relevant to childishness. It's childish to throw insults against reasoning. Haha anyway don't get worked up because I'm saying why I don't like it you can like it if you want to, don't get so angry because I said he's not in tune when he just clearly isn't. Your opinion is valid in that you like it, you can think what you want, but him singing correctly is just wrong.
Olly is awesome...never liked him when I was forced to watch him on the Xfactor but after seeing him a few times I thought he was a cool guy. When I first heard JT sing this is at 05:30am on my way to work i actually thought it was Olly and now he has covered it i like Ollys version better.
