I'd simply hesitate before basing your understanding of the English language on a song written to air dirty laundry.

Thank you for the clarification and the advice. It's just not practical as a non-native speaker to always be sure about the exact meanings of the words you use.

Also, there are by now more non-native speakers of English than native speakers in the world, so perhaps giving some benefit of the doubt is always a good idea.

You can understand how tough that is for a native speaker, though. Thanks for being reasonable about talking about it and being willing to learn!
