DJs play a large selection of tracks each gig. For artists, there is no guarantee that their latest banger will be played by the club’s DJ. Sure, the artist can try to finesse their way to the booth to hand the DJ a flash-drive, but that can be intrusive and annoying to the DJ. That’s where Spinfire comes in to play. Spinfire is an app for iOS and Android that allows DJs to sell “plays” during their sets. Artists can then pay DJs a fee ($20-$500) for them to play their tracks.
