I think that's a big trope in pop music: the blaze-of-glory breakup. It's not one that I particularly identify with, but it's definitely possible.
When I came up in a band - not just in a band, but a kind of underground DIY community - there was such a clear cut distinction between what pop was and what not pop was in very simplistic terms.
If I'm receiving an email from a stranger, I usually like it to be properly thoughtful and explanatory, and not just hitting someone up for a casual favor out of the blue who you've never met before. I really believe in manners.
