Promoting a mash-up artist

Hey guys, my friend has made some killer mash-ups from his computer and they're now on youtube. Wondering if you guys have any tips on how to promote this, or any help on getting some views to the videos. The mash-ups are pretty high quality and I don't know peoples taste but a lot of people in our school dig them. Let me know any ideas you guys have, thanks.

Lets see em I'm a big mash up fan I'll give you my thoughts on it.
