The Sonos home digital music streaming system has added built-in support for the Napster music subscription service. The feature is part of an upgrade that also includes new software, new devices, and new services.

Sonos users are able to access the entire Napster music catalog, via the Internet-connected device, without the need to stream it from a computer first. Sonos has a similar deal with Rhapsody.

The company also introduced a partnership with the Best Buy Music Store, also powered by Rhapsody. In addition to allowing Best Buy store users to stream their music directly to the device, Best Buy will also begin demonstrating the Sonos device on the sales floor at its many retail locations.

Finally, Sonos introduced the ZoneBridge, a device that connects various Sonos receivers to a wireless router.
