This is an awesome, simple system that allows you to easily call music up throughout your home by artist, song title, music type, etc. and you can see artist name/song title information on your remote, too! Or we can set this up at NO COST on many of your cell phones!!! See the 5 minute video demo on the top left side of the Sonos web site.
And, the best thing is that it doesn't cost tons of money! And we can set this up inexpensively throughout a home using portable units if you'd like for a very low installation fee (usally between $199 and $299).
