Their debut song is going to be instantly dated and doesn't have mass appeal. Their concept is extremely similar to kpop but so far it sounds as if their catchiness and song structure isn't at the same level. The boys are mostly cute, but still have a lot of proving to do - perhaps better songwriters with better ideas (a Facebook song won't mean **** in 5 years, if they last that long with the way boy band promotion and success has been in the USA), and perhaps studio editing that doesn't sound like it was done in Garage Band.
