How to watch music videos...

The time when the teaser/full music video is released will be annouced, normally it's midnight (KST).
Rather than wait for people to upload on Daum, then wait for people to convert it then can upload to Youtube, which it'll take a while, why not view it first hand? Especially when one is anxious, waiting can be tortuous.

Go to: http://www.gomtv.com/music/
You will be able to find newly released teaser/full music videos on that page.
Don't panic if the clock reaches midnight(KST) and you don't see the video.
Just keep refreshing! XD

Click on the video.
Click on

Then this will pop-out. Choose the second option

 

Then you can watch the video! (;
