Getting music to all the rooms of your home can be an expensive task, especially if you have to run wires. Sonos has been selling network multi-room music systems for a while now that can stream tunes wirelessly to speakers in any room of your home. Yesterday, Sonos announced a pair of new wireless music systems and it has announced a software update.

The Sonos 2.6 update is available free to all Sonos customers. To entice users to install the new software update Sonos is offering free music worth $200 to those apply the free upgrade or register a new Sonos system. New features with the update include support for SonosNet 2.0 and MIMO, support for larger music collections on NAS or PCs, and support for Mac Leopard OS.

Users will also get DRM-free tracks from three Sonos providers. Classical.com will give Sonos users one free album from its classical library, one from its Jazz library, and one from its world library. Sonos says that eMusic will give users 50 free tracks and one free audio book. LiveDownloads.com will give users ten full concert recordings from a catalog of over 100,000 tracks.
