Listen to Chris Brown on iHeartRadio | Listen to Tyga on iHeartRadio

Chris Brown and Tyga are racking up another collaboration mixtape.  Tyga's Fan of a Fan 2 mixtape with Chris Brown hits airwaves today. The pair wrapped up recording tracks for the album when Brown finished his last overseas tour. 

Last month Tyga opened up in a radio interview about recording with Brown.  He said they never record their collaboration tracks separately.  Instead, they opt to work together in the studio. 

That method seems to be paying off because the pair can bang out as many as four tracks in 30 minutes.  Tyga gives Brown most of the credit for their speed, saying that he's "fast while recording."  

Tyga and Brown released their last collaboration mixtape, Fan of a Fan, back in May 2010.
