Question about producers

So last night I found this site while looking to replace some stems that I managed to foobar, and it was pretty late so I glossed over the fact that this is primarily a DJ site.

I don't DJ, but I make loops and tracks (which resemble long loops). Is there a way for me to earn rep on the site by posting some of my original loops? I mean, is that of value to the community here, or would it be pointless and annoying and I should just pay.

Also, if there's a benevolent soul out there that has just the Intro Vox wav file for Matisyahu's - One Day I'd be appreciative.
