...And I suggested we jam out some songs for his practice between lessons. Thing is, I'm trying to pick some songs but I'm no drummer so I have no idea what makes a song difficult on the drums. His drum instructor has him playing "Back in Black" by ACDC to work on fundamentals and technique. I'd be game to play that, I dig some classic rock but my buddy wants something a touch more challenging. We both like stuff like Lamb of God, Avenged Sevenfold(me a little less so), Killswitch Engage, All That Remains, stuff to that tune. So I could use some song suggestions, somethin heavy but not too tough for the drums.

What does this have to do with electric guitar? In other words - you may have better luck with this in the drum section.
