Only now that he has passed will I actually start watching the Sopranos.
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.
Liking the series itself certainly donates to liking the theme song, I dont think it works 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.
