You guys are full of shit. Disposable Heroes is one of the best songs on MOP if not one of the best Metallica songs ever. Look, I used to be the hugest Metallica fan ever and I have spent a lot of time pondering over these songs and I'm pretty sure that Disposable Heroes is one of their least disposable songs!
They actually played in my town last Friday, the same day I graduated from college and all the guys at my work thought I was gonna go check that shit out because I'm the "metal guy" but I was like "fuck that shit, i lost all respect for that band years ago" and I felt really fucking kvlt when I said that.
