i think cyberpunk has transcended it's original purely literary usage, Nuclear_Device. Even wikipedia agrees =), cyberpunk has crossed over into the realms of various mediums like film, fashion and music. That said, cyberpunk is a great description for any electro/ebm group whose beats, rather than repetitively go oontz oontz and thought of as danceable, take on more of a martial/militant vibe (or even punk if you like). Obviously the term probably more directly refers to the meaning behind the group's ethos, however (sharing concepts with "dystopian" future with lots of machines and cyborgs, hence the name). I like to think it goes even further, borrowing dark or aggressive aesthetics from punk music (such as the attitude of the musicians or music; and more directly, the fashion sense that has directly influenced "rivethead culture"... [mohawks, neon hair and piercings anyone?]). Just my two cents, though. Think how you will.
