i must say vdj had a good idea selling at steam
http://store.steampowered.com/ i think mixvibes should sell Cross there .
as you many or many not know steam has millions of customers buying there games everyday
im one of them .
yes this would be copying vdj. but customers on steam would have 2 options . this would help mixvibes get better known fast .
djworx.com did a story on this here
