Well this would be kind of making this like MySpace. This is a gaming site, not My Space or Face Book. This is just my opinion, but others may have other opinions.
This site is dedicated specificly to games and its community. This site was never meant to be a place were you can do everything. It is, as I mentioned before, for games.
If you have a video you would like to share and there is another site people can go too to watch your video, feel free to post a link to the site. You can do the same for music.
PLEASE, be sure that the video (or music) and the website you are linking is apropriate before posting the link.
