Every once in a while, we go through a lot of tweets to find some of the not-nice things people write and we turn them over to the people they were written about. We've done it again for a new all music edition of #MeanTweets featuring Billie Eilish, Midland, Chance the Rapper, Luke Bryan, Perry Farrell, Green Day, Leon Bridges, Monsta X, John Mayer, Alice Cooper, Lizzo, Luke Combs and Cardi B.
