My favorite for a long time was Into the New World. But know that Paparazzi has come out, I'm really torn between those two. Both of them have really cool concepts and awesome dancing. I chose Paparazzi probably because it's the most recent one I've been watching.

I think Paparazzi! ^^

My favorite mv to date next would be Oh then RDR

always Gee, 2nd Echo

and Bad girl

Gee, Paparazzi, Time Machine, Hoot, Oh!, and the Boys.

Always the boys.

I think the Taxi dance video was particularly well done. So much Sooyoung.

I really loved Genie after i first watched it^^ SM released it right after Gee. it just showed how much they matured within those 5 months<3 and in The boys.^^
