What is your favourite show theme song?

Oh I love the theme from Doctor Who. The 2008 theme was great but I preferred the 2005-2007 version. I became a fan of Doctor Who in 2007 so I associate that theme with the show a bit more. The amazing thing is, the theme sounds good even when it's played backwards!!!

I'm also fond of the theme from MASH. The lyrics are quite disturbing (depending on how you interpret it really...) but I quite like it. Though on the TV series they only used an instrumental version of this song.

By the way, one of my favourite videos on youtube is by a user called “ReverseThePolarity”. They do great work! Most of my favourites are done by that youtube user. But check out this:
