Could the next big D2C stores for musicians be cloud services like Dropbox and Google Drive? That’s the thinking behind a Polish startup called Sellbox, which lets people sell files from their cloud storage, promoting them on Twitter and Facebook. “Sell your eBook, Music, Image, Game… in seconds,” encourages its website. The seller sets the price, payments are handled through PayPal, and Sellbox takes a 5% cut of the transaction. Spotting the downside yet? Yes, anyone can sign up for Sellbox: in theory selling their (copyrighted) music collection. “Sellbox does not pre-screen Content, but Sellbox has the right (but not the obligation) in their sole discretion to refuse or remove any Content that is available via the Service,” claims the terms and conditions, although the fact that a distinctly unofficial ‘Angry Birds Menu’ is one of the featured files on its homepage hints at possible copyright arguments ahead. In truth, we wonder why Sellbox would appeal to a musician over, say, Bandcamp.
