Hey, I've made lots of mashups and I can make them on requests.
So I was thinking about...Could I sell my mashups to djs who plays them live? There are any online services for this?
I don't own the copyright of that music, I wasn't saying I'm going to put them in official stores of course, just to "private djs".

Otherwords...does a "mashupper" (man who make mashups for artists) exists? Or it's just a story for children?

 

this kinda goes the direction of ghost producing, probably you have to dig that scene to find people interested in this.
but i think most do it for themselves, that makes the area for business very small

Spoiler: from Wikipedia

A mashup (also mesh, mash up, mash-up, blend, bootleg and bastard pop/rock) is a creative work, usually in a form of a song, created by blending two or more pre-recorded songs, usually by overlaying the vocal track of one song seamlessly over the instrumental track of another.To the extent that such works are "transformative" of original content, in the United States they may find protection from copyright claims under the "fair use" doctrine of copyright law.

today, if you find a buyer, you can sell anything

 

All clear, so I imagine I may find kind of online shops for mashups...

 

you don't own the right of the music used you can sell nothing online ..unless do re-edit or remix renamed them and sells them like their originals..actually this is a thing in beatport and juno
