Yeah, it sounds like shit.
"A new music genre for the era of 2009 - 2012 (tweens)... If you have kids now, they're probably listening to it" - South Park s15e07
It's most notable list of mutated infants include Justin Beiber, Jonas Brothers, and the entire cast of Glee (except Jane Lynch).
Signs you are listening to Tween Wave music: When all you can hear is someone ripping ass into the microphone over a drumbeat. More precisely when it sounds like shit is spilling out of the speakers and puddling on the floor.

"I don't know, but he gets up there and strums a geetar and starts loadin' up his britches up like it's goin' out of style... It's like some sort of 'britches holocaust'... he calls it Tween Wave" - 1
Thanks South Park!
