Disco also was a reaction against both the domination of rock music and the stigmatization of dance music by the counterculture during this period. Women embraced disco as well, and the music eventually expanded to several other marginalized communities of the time.

New wave music is a musical genre created in the late 1970s to mid-1980s with ties to 1970s punk rock.

Initially—as with the later post-punk—new wave was broadly analogous to punk rock before branching as a distinctly identified genre, incorporating electronic and experimental music, mod, disco and pop. It subsequently engendered subgenres and fusions, including synthpop, college rock and gothic rock(Wiki).
