Star actor and Captain America Anthony Mackie has made a pretty big revelation about Kendrick Lamar. Mackie revealed that Kendrick Lamar performs the title track for the movie, presumably called ‘Brave New World’ and is dropping this Friday along with the movie. This is interesting timing due to his arch rival Drake dropping a new album with PARTYNEXTDOOR Friday as well. But, keep in mind, the movie is coming out Friday as well so it does make sense for the movie’s team to drop the song when the film is released.
