Always write true statements. People can’t argue with truth. It’s real and affects people, even if they don’t like it, it affects them. Even if you’d want to use metaphors in your lyrics, use them the way that sounds real. Stay away from unnecessary exaggerations and be frank with yourself, defining if you’re writing real or just trying to be clever.
Again, not many artists are interested in getting up every night on stage and singing about being a cheater, a drunk, a jerk in general or any negative thing. People buy less t-shirts from cheaters, drunks and jerks. The artists want the audience to think they are hip and cool people. Paint them any other way and your chances go down to almost zero.
