Sometimes ad people are capable of weaving good music into their adverts in a way that kinda enhances everything, so when such a successful synthesis occurs, I think its worth flagging up.
This is Water Fountain by Tune Yards, a song that builds towards an epically bonkers soundclashing crescendo that the crystalline soundwaves in this Sonos ad complement perfectly.
Having said that, if you think this is crazy, wait until you see the original music video.
