Iconic and undeniably brilliant, this theme will go down in television history. I've never been a fan of metal, rock or anything remotely guitary, but this song is 100% on my iPod, fuelling me on my way whilst on the treadmill at the gym. I challenge any one of you to argue that the chorus to this is anything other than perfection. Rousing and entirely upbeat, this theme tune used to make me feel untouchable and always made me crave my red Ranger outfit from my parents, a present that never came.
