A Song that Comes From a Boys Group

I Knew It - BEAST

This song. ASDFJKL;. It's really the song that cemented my fangirl status as a B2UTY. Before this song, I was like, "OUUU! YOSEOB IS ADORKABLE, OTL." But after I Knew It came out, I just fell in love.

Other songs would be like All Day Long (ZE:A), Rock Ya Body (UKISS), U Hoo Hoo (Block B), Smile (Click B), Grain of Memory (Fly to the Sky), I Can't (2PM) and many more. But I've refrained from putting up songs like Beautiful Hangover, It's You, Replay, I Was Wrong, Fiction, Nanlina, and other songs that are already quite popular.
