Via Wiki: "Post-punk was a popular musical movement in the mid to late 1970s, following on the heels of the initial punk rock explosion of the early 1970s. The genre retains its roots in the punk movement but is more introverted, complex and experimental. Post-punk laid the groundwork for alternative rock by broadening the range of punk and underground music, incorporating elements of Krautrock (particularly the use of synthesizers and extensive repetition), Jamaican dub music (specifically in bass guitar), American funk, studio experimentation, and even punk's traditional polar opposite, disco, into the genre.

It found a firm place in the 1980s indie scene, and led to the development of genres such as gothic rock, industrial music and alternative rock. Post-punk's biggest influence remains in the vast variety of sounds and styles it pioneered, many of which proved very influential in the later alternative rock scene."

I'm going to go out on a limb here and suggest that among these handful of songs, a bridge was built from 'punk' to 'post punk'. Not these songs specifically and/or in this particular order, but there's a maturation process here that begins say, with Gen X and traverses that bridge via Wire and The Cure, and gets us to Gang of Four with a late night butt wiggle via Ian Dury. (Am I over-caffeinated this morning?)
