What song is this.?

Teenage Dream. That's an easy one! ^-^ I thought you were gonna have a song that no one knew like Dragostea Din Tei, (better known as Numa Numa) not something that everyone knows! XD

Hora kimi no sugu me no mae ni iru, sono namae wo saa, itte goran kono boku no namae wo! eFTo

↑ Now ya see, THAT'S a "name this song" worthy post. ^-^

Hora kimi no sugu me no mae ni iru, sono namae wo saa, itte goran kono boku no namae wo! eFTo
