SHINee is as popular a boy group as ever!

They dropped their groovy, retro MV for "1 of 1" just yesterday, but in less than 24 hours have gotten over 1 million views on YouTube!

The MV is fun with the boys in retro, colorful attire while dancing with a large group of stunning ladies.  The dance moves seem fun, too.  If you missed out, watch the MV above!
