Say you write a song about someone while you are in a relationship with them, but then you break up.
How hard is it to keep singing it-do you take it off of your subsequent playlists? Do you have to distance yourself emotionally from the material to get through? Or does singing it bring a sort of catharsis for you? Or is worrying about whether the lyrics are still personally meaningful to you or not utterly beside the point of making and playing music?
