Music for or by tweens.

a. Just another Disney channel money making tool that will make Disney money and like most Disney stars, be tossed aside when they starts to fall short of the marketing profits.

b. A band of preppy males who are targeted only towards the tween audience, and have been endorsed by Disney channel.

c. Tween music

D. Need I say more?

Parent's don't get it.

(from the south park episode where the kids think the parent's music sound literally like crap, and vice-versa)

On June 8, 2011, South Park brought attention to this pandemic of "shitty" music which is plaguing our world.

"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.

Simply: it's popular music from 2009 to 2012. Coined by the creators of South Park in the episode "You're getting old." They are not making fun of a specific band, artist, or anything like that (maybe dubstep would be the best genre to describe tween wave). People are over-thinking this making it seem like they are ripping on Justin Bieber or something, but its a simple definition idiots.

1. a member of a generic corporate shitass pop group that hit it big in the late 90s and early 00s. Nobody likes them except tween and teen girls who have godawful taste in music.

2. a young teen boy or a 20-something Gen Y man who follows along with whatever shit the idiots in suits dish out, gets a stupid haircut for a couple of bucks, doesn't know anything about rock'n'roll culture, likes Ally McBeal and basically wastes his life away.

Another new boy-band that is liked by tween girls who use lots of smileys when they write something. Their lead singer, Joe Jonas, basically just whispers and yells and it is counted as singing. If you have friends who like this band, be worried. Try to make them listen to real music so that they realize what crap the Jonas Brothers are.
