Hm, I don't really care for Biebs' music, but I don't see what warrants all the Bieber-hate, lol. He is just a current trend, and nothing more, however I feel that his rise to fame and talent are more legitimate since his popularity before stardom actually started on YouTube due to one of his piano videos getting crazy high views and ratings. There's not much use in hating the trends since there will always be Justin Biebers and Soulja Boys and whatever the hell else is "all the rage" right now.
But if you must indicate a target for your hate and irritation, I recommend directing it to someone like Lady GaGa or however you spell it. I can't tell you how much I've pondered the realization that being forced to hear Lady GaGa's nonsense playing in my cousin's car for 2 hours was one of the greatest misfortunes of my life.
