First . . . I'm no expert. However . . .
Yes, I do that a lot with popular music. Very seldom if ever with classical.
One interesting thing has to do with misprints in the sheet music.
Not often, but a few times, my teacher would stop me and say, "play that again." Meaning just a phrase . . . a couple of measures.
Then she would say, "that's wrong. That's sharped (or flatted) but the music has omitted the accidental."
My teacher has a full music education, including enough theory so she knows what is happening with key changes.
We write in the accidental and almost always the chord sounds so much better . . .
So . . . never say never on some of these minor changes.
Misprints DO occur. Some music publishers are very diligent, some are marginal. Trust your ears, and then . . . ask your teacher.
