"Are You In?" is the fourth single from Incubus 4th full-length album Morning View. In New Zealand it peaked at number 5 and was certified gold. The song itself has elements of different styles in it, including jazz and swing music. The liner notes for the album contain no lyrics to this song (which all other songs have), most likely because there are very few lyrics. Although the words are very simple, it has become a fan favourite and a staple during live performances.
