In the song "Love Yourself" in which you are quoting. He says "Mama don't like you, she likes everyone." He's clearly saying how his mother doesn't even like the person but she normally likes everyone, stating there's clearly something wrong with the person he is referring to. Thank you for this warm-up it will help with my further debates.
yes it does refer to a messed up person but still love yourself is suppose to mean love your self and my momma dont like u and she loves every one does not make any sense , the song has lots of mixed meanings its suppose to mean love your self but u also describes someone who loves lots of people hates you which means your messed up but love yourself mr beiber doesn't make any sense
