ALL CAPS is how MF DOOM wants you to spell his name. Originated from a line from MF DOOM's 2004 album, "Madvilliany," in this album there is a song titled, "ALL CAPS," and in it MF DOOM states, "Just remember ALL CAPS when you spell the man name." In this song he specifies that he wants people and his audience to spell his name in ALL Capital letters.
