Okay, so by now you probably know it's someone's birthday. Someone really famous, someone who most people love and make fun of? That's right. It's KE$HA's birthday! Wait, what? You were thinking of Bieber? Oh, yeah. Yay. So in celebration of KE$HA's (and Bieber's) birthday, please enjoy Len singing 'Baby' and Oliver singing 'Set Fire to the Rain'! Yeah, Vocaloids CANNOT sing KE$HA.
