As many have noted, MTV doesn't play videos anymore, focusing instead on reality shows and other types of content, but the channel does still boast arguably the largest collection of music videos anywhere. Today, the channel announced the launch of MTV Music, a YouTube-styled site which will eventually feature the company's entire catalog of music videos.
As of today, there are 16,000 videos, "Unplugged" performances and exclusive MTV concert footage. Sadly, the site maintains MTV's habit of regional restrictions meaning it is impossible to stream the videos outside of the United States. While every video is not available yet, the site has pages full of videos for artists like Bad Religion, Rancid, Blink-182, New Found Glory, Less Than Jake, AFI, Sick of It All and many more.
