1) Devin Townsend
2) DGM
3) Lemon Jelly
4) Extreme
5) Opeth
Though this list is highly susceptible to change. Other's considered: Boards of Canada, Dream Theater, Michael Jackson, Regina Specktor, Thin Lizzy, The Reverand Horton Heat, Children of Bodom, Elton John, Incognito, Ayreon, and Dragonland. Oh, and I guess Daft Punk, though Discovery/Interstella 5555 is the only album I love, but I reeeeaally love it!
