There will be a halftime concert at the National Title Game, and it will be Bruno Mars. There is no sourcing on this, and no inside information, and we don’t need any. It will be Bruno Mars, because the default choice for any broad consumer event’s soundtrack in the years 2017-18 is Bruno Mars. Accept it. It’s Bruno Mars for the rest of your life, at every turn, whether you like it or not.
Don’t attempt to fight it. Look at him and realize how doomed you are to even consider fighting it.
