hmm, definitly Crimson Winds when Anders come back from that fast verse and screams "My sweet Norderlaaaaaaaaaand!!" and that sweet riff starts up. Beautiful.
Also I think another one would be a part of Projector song, which I completely have forgotten cause its 645 am and im way to tired to go find. It might be at the end of Auctioned (my favorite Projector song), where he sais "Where did I sign, did I miss the auction where my life went under the club". That might possibly be it but im not gonna go pop the cd in cause im too tired.
For overall songs, its gotta be The Same, Haven, Auctioned, Lethe, Crimson Winds, way to numerous. But those are the two direct parts that just give me chills.
