Nottingham Lace by Buckethead (a six minutes and thirty three instrumental songs mainly dominated by three and a half fast guitar solo, this song makes me appreciate music so much more with it's structure and the technique used to compose the song, simply magical especially the parts where it builds to something huge -the guilat solo- it will be my number one song ever)
Gloomy Sunday (The Hungarian Suicide Song) by Rezso Seress (or Billie Holiday) ever heard of this infamous song for it's notorious reputation of the song that makes people commit suicide? i really adore the lyrics, and the haunting melody.
Hallowed Be Thy Name By. Iron Maiden. This is one those songs that lives up to the word: Epic
