That cartoon is only true for people who are only interested in music from the 70’s..
People within the musical environments where i like to hang out could not disagree more, myself included..
The 70’s are by far my less favorite decade regarding basically everything..
And musically, the only really nice things that happened were some nice funk, punk, new wave (late 70’s) and Steely Dan..
I am sure I forget a few nice things now, like Rickie Lee Jones and some Joni Mitchell records..
Maybe the 70’s were not that bad after all, if all the typical classic rock (Boston, Cheap Trick, etc), disco and Queen can just be ignored and left out..lol..
