The two innovative companies announced last night that they'll be partnering up. Sonos owners will get a free trial subscription to Pandora, then can subscribe for $36 a year.

Pandora offers what it calls the Music Genome Project, in which "highly-trained musicians analyze songs, one at a time, using close to 400 musical traits including melody, harmony, instrumentation, rhythm, vocals, lyrics, and more to automatically build a station with songs that share interesting musical similarities." Users of Sonos (a PC Magazine Editors' Choice winner) will be able to access the trial via the newly released 2.2 Sonos Software, right through their Sonos handheld controller, so no PC required. Once upgraded, they can listen to up to 100 personalized Web radio stations, and can program different types of music for different "zones" within the house.
