The film follows Pat Solitano (Bradley Cooper), a young man who has just been released from a mental institution after spending several months there for attacking his wife's lover. Pat is required to wear a GPS ankle monitor and move in with his parents, Dolores (Brea Grant) and Pat Sr. (Robert DeNiro).
The piece you're referring to is likely a musical composition. In the 2012 film "Silver Linings Playbook," there is a notable piece called "The Silver Lining" or more commonly, "Silver Linings" but I couldn't find info on a specific 2013 piece. However, I can tell you that the movie features a memorable scene where the characters dance to the song "Silver Linings" but I believe you are referring to a musical piece by Joseph Gordon Levitt - "Silver Linings Playbook 2013" dance sequence features to "The Man I Love" by Stacy Kent but was replaced - but actually features "Silver Linings" By Stacy Kent silver linings playbook -2013-
