Hello, this is some youtube guy called SingingDork888. Man, you should hear him sing. Hardcore Rihanna :D He pwns Rihanna! (i feel like hardcore asianese. Shit) Oh ya, by the way, it's quite unexpected of him to sing this song. So yup, Subscribe to him in youtube if possible!
P.s. ARGHHH I can't believe he sings so well and he's work as a pharmacist! What a waste!
