What an intriguing piece. I caught this the very second it dropped.
Your musical collection says a lot about you @donkeypong. You are simply a "dope guy", in every cool sense of that word. Quite a versatile musical background you had growing up.
As for the issue with Monday, you stole my thoughts completely, with your last two paragraphs.....
Regardless of whatever day, the week is made to start on, just to satisfy "Monday-Haters", the supposed "new" first working day of the week will eventually get hated as well.
The problem with Monday isn't the day itself, I believe. People that loath Monday, probably loath "their work", and the "job and responsibilities" they have to do on that very Monday....not necessarily, because it is Monday.
If for instance, the work week starts on Sunday, and Weekend begins on Thursday, running through to Saturday....Sunday would become the new day to be dreaded or hated.
So, like you adequately summarized in this post....

There’s no cure for the blues at the beginning of the week. And the same quantity of work still needs to get done, whenever you choose to do it. Short of creating a 7-day weekend with no work at all, that early week angst is likely to continue on whatever day that week begins.

Mondays isn't the problem, People's Jobs and Responsibilities on that Monday is what they hate and dread.
To think of it, if you do enjoy your job, you wouldn't dread doing it. Regardless of whatever day you have to do it.

I better stop here. This is turning into a post of its own....Lolz
Thanks for exposing us to your cool '80s musical collection. Like I said, you are a "dope guy" @donkeypong.
