I'm assuming all of you guys are talking about what songs you can play on the guitar. That's pretty good guys, some of you have a respectable list. On the drums I can play;
Ok, well, I can play all songs but that's just making up stuff, and keeping time, I might not have the exact drum fill, If I didn't learn the song. I know all songs good enough to not fuck up, from all albums, maybe except Orchid. But what I can play exactly;
Deliverance
The Drapery Falls
Blackwater Park (if I have the energy for the prolonged double bass at the end)
The Leper Affinity
Harvest
The Funeral Portrait
Demon Of The Fall
Face Of Melinda
Bleak
When
April Ethereal (maybe not, I can kind of play it)
The Amen Corner
All of Damnation.
I think that's it. Anyway, I just want to say this is all pretty much high energy playing except for Damnation. And sometimes I try to play it and just can't, for exhaustion reasons, then I get really pissed off and all depressed, lol.
[edit] Oh, and as for hardest song, I would have to say......I don't know let me listen to a few songs I think are hard, and edit again. But I'm probably going to say something off of Still Life.
