Post-punk was by and large a reaction to the artistic aspects of punk music. To post-punk musicians, punk had the spirit, but also terribly formulaic, simple, and repetitive music of low quality. Through this motivation, bands experimented with sound more, took the punk ideology and brought it into an expansive range of expression. This is also where many huge subgenres came from, such as synth punk, gothic rock, jangle pop, no wave, and many others. This change effectively undermined the popularity of regular punk music and brought in a new period of "hey, I guess punk music doesn't have to sound unsophisticated or uncreative"
