Christians seem to like Coldplay. I'm not entirely sure why, but they do sound quite similar to a lot of worship music.
Again, I'm not sure of the reasons, but Chris Martin (the frontman) seems to get a lot of stick.
I don't hold any particularly strong views on Chris or his band, but I found this quote from the BBC hilarious:
"Radio 1 also apologised on-air immediately after Bono used an expletive to describe Coldplay's lead singer Chris Martin.
The BBC said it had received no complaints about it."
