I love this business model. DJs cut licensing deals directly with independent musicians and labels, load up iPods with custom mixes, and rent the iPods to cafes and stores for a fraction of what it might cost for them to license something similar from Muzak. What I'd love to see is for the players involved to play a bigger game and tie some in-store point of purchase displays, so you can actually buy the music you're hearing. (Nothing annoys me so much as a place where the staff have no way of knowing what's on their own sound system.)
