Crazy is a R&B love song by duo K-Ci & JoJo. It was released in 2001 and was their first single off the album X. It was also featured on the soundtrack to the hit dance film Save the Last Dance, starring Julia Stiles and Sean Patrick Thomas. The song is notable for making prominent use of auto-tune years before it became popular.
The official music video shows what "Crazy" is about. It depicts a lover who ruminates over the poor choices he made that caused his girlfriend to break up with him. The song talks about losing sleep over it and after realizing the pain he has caused his girlfriend, he must choose between her and his life as a criminal. Once he chooses his criminal friends over her, he eventually regrets his decision and wishes to return to her. The video was directed by Terry Heller.
