I also loathe the theme song they use at beginning, seems totally out of place.
The whole show is filled with muzak and soft easy listening music (elevator music) which is what one might imagine a place like that playing. Now it comes off as ironic contrasting with the real nature of what is going on. I suppose with all the talk of unoriginality it doesn't help that they did something similar in Lost now that I think about it (though not the theme song).
