Popstar: Never Stop Never Stopping

I don't get the title Popstar: Never Stop Never Stopping. I also realize that I am not the audience for the music in this movie. The story of fame and success in the music industry is not new, but it is funny and corny here. Lonely Island's performance at the end was the only song I appreciated, as this is a hard R comedy. I'm guessing that in the end, I got it. An OK rental.
