I like unnamed artwork. It adds anonymity and interpretation and openness. Would Song 2 under the name "Pleased To Meet You" have been the same thing? Would Beethoven's fifth symphony have had the same impact as "Thunder in Eb"? To name it is to take ownership but leaving it anonymous is to give it to the people on the other end of the art. Elliot Smith gave an amount of songs numbers instead of names so that you didn't know what you were getting into until you herd it. Who can say if No Name No. 5 is a love song or an angry song until you've herd it. Led Zeppelin went even further and gave their fourth album no name at all. Manny people call it Led Zeppelin IV, others call ZOSO and Robert Plant says he just thinks of it as the fourth album. And that just works for me.
