It's a tough process to choose my top five but at the end of the day it comes down to essentially three points of measurement. First, I have to be able to watch an entire season back to back and not once want to skip the theme song. Ever. Second, if you came up to me and asked me to hum or sing a particular theme song, I could do it without thinking twice. Third, I would buy each one of those theme songs and put them in my heavy metal playlist regardless of the genre. With those judgement points out of the way, let's get to it. Find my picks, in ascending order of course, after the break.
