I don't know if it's just me but have other people noticed different writers over-using the word "Stygian" to refer to deep bass from speakers, etc.? Is this a newly coined cliche or has it always been used in audio-speak? It's pretty lame and annoying. Aside from the fact that Styx runs in the mythological "under"world (har har), what the hell does it have to do with bass? Did the sound of its waves register at 16 Hz according to Hesiod or something?
