I believe any sound can be music, as long I enjoy listening to it. But the second I’m forced to listen to something that I don’t want to hear, I get really annoyed.
I think this is the second appearance of the logo for Orneryboy’s favourite band-that-I-made-up, The Death Ducks (Die Todesenten in German, assuming I got my translation right). I forgot to comment on this the first time it appeared. Other than their logo, the band never made an appearance in the comic, but I always imagined that they would sound like early Einstürzende Neubauten — hence their German name, and that sweet, soothing “klink bang kong klang” sound.
