Ok, there are a few problems with this...
1.) Why would I let someone else, who could possibly make money off of it, upload my music?
2.) Your videos do not get very many views.
3.) Why shouldn't I upload my stuff myself?
4.) If you upload it, I can't put in the description I want, the images I want, or the tags I want.
Simply put, I just don't see any reason why I should let you upload my music on youtube... because I can just do it myself and customize it as much as I want. I appreciate the kind gesture, but it is kind of silly. I upload my best songs on youtube already, and so far have gotten fairly good exposure by myself.
