I've not given this too much thought before but it doesn't bother me really, like others have said if they overdo it or try to push a religion then I can't be bothered with it.
Slightly related I guess, I always find it annoying when you buy an album, look inside the booklet or album notes and the first thing you see is "First and foremost, I want to thank GOD", it is then followed by family members, fans (who bought the album) and the production team
