> don't you hear the person's voice & the sound of the voice makes you think of the person & if you think of a person who makes you sick, it's gonna remind you how much they make you sick. so yeah, you can say you separate it, but realistically how much do you actually separate

I find this depends on what the artist is singing about. If it's something completely incongruent with their behaviour or beliefs, like say Chris Brown singing about women, I have to switch the song off.

But if it's something entirely unrelated, I don't really tend to get those thoughts as much.
