Ok, the legendary classic. I'm going to give it a 7. Why? Because i heard it like a million times in million live versions. When you hear three same riffs a million times, the enthusiasm for the song drops. Yes it's brilliant moment live, i've jumped around and ripped off my own vocal cords at chorus, however i also behaved like that when they played "Iron Maiden" - and you can check that topic to see what kind of score i gave to that song. I'm bit sick and tired of this track. But there is no chance that it'll ever get lower than 7 out of 10 in my book, it's an excellent heavy metal classic, ruined by overplaying.
