I see nobody opened a thread about it yet. So here we go ;)
This genre originated first around 1977 in the UK, its badly played music was a reaction to all the elitism and virtuosity Rock had led to, take the Pink Floyd as an example, and the first band who became famous and spread its ideals was the Sex Pistols, whose lyrics were often slagging off authorities and inviting people to use their own brain and think outside of the box.
Thus I'm gonna start with three songs from the very first wave of Punk Rock.
