British Gas probably have the worst phone line hold music/information EVER!
They have managed to make some sort of Jive Bunny esque 'mega mix' of something that sounds a bit like the intro to a Coldplay song off the second album, a bit of the verse of a Coldplay song from the third album and the intro to Everybody Wants to Rule the World.
In between this they keep telling you hints about how to save electricity, but these sometimes just burst in on each other.
Infuriating.
