"We're rooting for them," said Mieko Kusano, Director of Product Management at Sonos in a meeting with CNET UK. "They are one of the companies we're interested in working with." It'd be an awesome move. Sonos already supports unlimited streaming from Napster, but for a cost. Imagine a Sonos music system with unlimited music, but for free. That's something Apple can't currently threaten with its iTunes/AirPort Express/iPhone Remote app ecosystem, and nor can the Squeezebox. But Spotify's ad-supported streaming service can."
