I haven't configured the user upload module but you can upload tracks via ftp and I'll add them to the appropriate section. Feel free to suggest category names, genres, etc.

send me an email: beatmassa@gmail.com and I'll reply with the username/password and all that other jazz so you can upload your shizzle.

Also, please note that you can include art work with each track, for categories, etc. As a matter of fact both the video and audio player let you use custom backgrounds - these backgrounds can be .png, .gif, .swf - so if you have something that you think would rock as a background let me know and we'll toss it up there.
