Inspired by discussions in this very forum, I gave Spotify a try for the first time at the weekend. I was delighted to find they had an album by The Chameleons which I don't have and had never heard, I lined it up and listened to the whole thing - fab!
My seven year old son, playing on the floor popped up with a bemused expression when the music was briefly replaced by British Gas adverts but I didn't find it too intrusive. Thought sound quality very good, worked well on wireless. Good stuff.
