Spotify has reached the scale now where its business is the subject of new rumours every week. Two more reared their head yesterday, starting with speculation that Coca-Cola is in discussions about investing $10m in Spotify to build on the two companies’ strategic partnership. Billboard, Sky News and Business Week all claim to have multiple sources telling them about the negotiations. The stake would be small – Spotify is thought to be seeking up to $200m in its next funding round – but a significant marker of Coca-Cola’s ongoing music intentions. Today’s second rumour concerns Spotify’s global expansion, with PaidContent claiming the streaming service is in talks to launch in Japan early next year, following Sony’s Music Unlimited into a market traditionally more focused on downloads than streaming.
