Re: Whatever happened to Theme Show Music?
I like TV theme songs. Good intro music will get me to try a show. And I prefer to watch the intro song for every episode, whether it's live, Tivo'd or on DVD. (My wife, however, prefers to skip the themes

)
But I've enjoyed the recent changes. As long as the creators create the right sonic signature for the show, I'll enjoy it, whether it's short and simple or long and complex. My favorites are those like the incredible, unique music for BSG. But the sonic blur of Lost is also great.
No, "Lost" won't be on theme-song CD and isn't hummable. But that's not the point, is it? The purpose is to grab the viewer and introduce the show. Everything else is secondary.
