To my ears, "I don't play politics" translates to one of the following:
1) I'm not good with people and I will burn bridges.
2) I deal with stress poorly and I will cause drama.
3) I'm very good at politics and I play dirty.
"I don't play politics" is a red-flag statement for me.
Unless you're interacting solely with your instrument or DAW, you're dealing with politics.
Politics is the art of accomplishing your goals while keeping the most allies possible. This is a flexible statement for a reason.
Humans are composed of moods, feelings, hunches and many other idiosyncracies that color every single interaction. If you're alive, bias is inevitible.
It's never just about your raw skill. In fact, according to MIT researcher Thomas Malone, it's the groups' intrapersonal skills that determine their collective talent, not the "average" of their talent levels. This is why so many supergroups end up as a disappointment.
Imagine you're a highly regarded promoter with bands approaching you every second of every day. Would you rather give a leg up to the band you hung out with after a couple shows, or "Band #1093703"? Whether you believe this is wrong or right, this is how the world functions.
Public relations is simply politics on a wider scale.
Your political skills will play a large part in your eventual success or failure in business dealings.
Pay attention to your relationships with others.
