Wanna hear some good music, click my name.  I do vocals and rythym guitar, and my homie Kunihisa from Japan plays the sickest guitar solos I have ever heard.  That is the power of youtube.  How else would I meet a guy from Japan, who lives in Japan, and be able to collaborate on music with him without ever physically meeting him?  I love this shit.  Youtube is a very powerfull tool, not just for music, but also for education and social awareness.
