Thier are loads of Amadeus bits on the first two Bodom albums
Red Light in my eyes pt2 intro is from "Mozarts 24th symphony" and their is a riff from "Requiem"
The breakdown in Hatebreeder is from "The Magic Flute" and another melody is from "Queen of the night Aria"
Some melodies in Black Widow are from one of his Concertos
Saleri's "from now on we are enemies" is at the start of Warheart
"Kill me, hurt me, fuck me, rape me" in Towards Dead End is from some opera by Mozart,I think its The Magic Flute.
Thats about all I can remember,The end of "In The Shadows" is from some classical song,no idea what though,Yngwie uses it aswell,I think it makes Amadeus much better if your a COB fan
Alexi Laiho is also a big fan of Hans Zimmer,The breakdown in Bodom after Midnight is from the movie "the Rock" aswell as "Hummel gets the Rocket" which is the intro to Touch like angel of death on Tokyo warhearts.
