Courtney Barnett performed her song ?Nobody Really Cares If You Don?t Go to the Party? on The Late Show With Stephen Colbert this week. The song sends a positive message to all of the introverts out there with uptempo lyrics like, ?I wanna go out, but I want to stay home.? Barnett elaborated on the song by saying ?It kind of feels nice because of the type of music I play, and where I?ve come from, like putting out my own records, runny my record label from my house still in Australia.?
