I'll listen to anything, but I tend to listen to pop, rock, folk, metal, and electronica. Mainly indie stuff.
So, stuff like Kerli, Coldplay, Coheed and Cambria, Imogen Heap, Daughter, IIRIS, monaca:factory/10 Years-P, Kyary Pamyu Pamyu, Asian Kung-Fu Generation, Paramore, No Doubt, etc. (So weird, I know)
