You wont be disappointed trust me, even those who this genre is not their cup of tea agree that it's one of the best series ever made.
Edit: I find that most series I like have badass theme songs... I wonder if I like the songs because I like the series or if it's the other way around?

Maybe, but then again it is one of the first things that you hear, so maybe it draws you into the series.
