Sorely tempted as I am just to list GY!BE's core discography and leave it at that, I'll actually choose five artists
Godspeed You! Black Emperor - Lift Your Skinny Fists Like Antennas to Heaven
Moonsorrow - Viides luku - Hävitetty (my remastered version)
Enslaved - Mardraum: Beyond the Within (my remastered version)
Genesis - The Lamb Lies Down on Broadway
The Mars Volta - Frances the Mute (my remastered version)
I think I could live with those, though the urge to list another twenty albums just to spite the idea of having to listen to only five albums for the rest of my life is mightily tempting. Really, though, I never go anywhere without my iPod and phone (which have 26,000 songs between them), so this scenario is kind of unlikely
