The duo behind The Driver Era, Rocky and Ross Lynch, are some of the hottest musicians we know. We asked the brothers to try to remember all the lyrics to 2019's chart-topping songs. We quizzed them on all our favorite songs from the year, from Billie Eilish to Lil Nas X. TBH, Ross and Rocky maybe should have listened to the radio a little more this year, but we still love them!
