BANSHEE!!! Song is so amazing. And its interactive. Each episode has a different lock combination that you can enter on the website for more content on the show. Oh and the pictures tell a story throughout the season.
I really enjoyed The Avengers: Earth's Mightiest Heroes (I think thats what its called) Season 1 opening song. I'd rock out to it every time it came on lol...ok, not literally but try and sing it.
I also liked the music from Dexter. The visuals were witty for the first few times watching. I'm surprised Michael C. Hall didnt change it to him singing a song with women draped all over him.
Game of Thrones is fun because they'll throw a new kingdom in there sometimes and I need to rewind it to catch the name and where it's at on the map. "oh sh-t what was that!?!"
Every time they show the smoldering ruins of Winterfell I think they should have a sign up saying "Nobody's home".
