Y'all are messy.
I love Rih but she didn't start no damn trend. I wasn't even aware one existed.

'Cause one doesn't.
Just 'cause she experimented with the sound and Britney did it after (Britney also experimented a bit before) doesn't mean there's a trend... Ke$ha and Nicki Minaj? Because they did a Remix?
Messy. No trend. It's barely even catching on.
A trend would be the use of autotune or those annoying repetitive bits in pop songs that started occurring a lot in 2006.
