The Sonos adverts are really very slick, this one featuring Paul Rudd and Rashida Jones and a clip from "I love You, Man" really strikes a chord with me.
Personally, I enjoy nothing more than listening to music on my sound system. That chill that runs down your spine when Adele hits those special notes, the way that the hair on the back of your neck stands up and you get goosebumps - You aren't going to get that on a cheap system, or listening on your laptop.
And you know what, you're missing out. Really, Nothing can relax you or provoke emotion the same as great music, and it's not about volume, it's about depth and nuance. So if you haven't already got a great sounding music system, get one and enjoy listening to your music on a whole new level.
