We don't know about you, but when the air turns crisp, we've just gotta keep things fresh in other areas -- like with a whole list of new songs on the radio in September 2011.

This month, we've got JoJo's latest, 'Disaster,' which isn't such a disaster after all. We gave it three stars, because it reminds us of old school JoJo, and everyone loves to reminisce about the good ol' days. Also on the airwaves in September, LMFAO pumps it up with terrible lyrics and a monotonous chorus in 'Sexy and I Know It.'

Kreayshawn really gets the drinks flowing with her new one, 'Rum & Coke,' just in time for The-Dream to declare, 'Wake Me When It's Over.' Keep it tuned to PopCrush all month long, because we’ll be uploading all of the new songs on the radio in September 2011 right here -- so you'll never have to wait to hear them while you're in the car.
