Worker policing is a behavior seen in colonies of social hymenopterans (ants, bees, and wasps) whereby worker females eat or remove eggs that have been laid by other workers rather than those laid by a queen.
 Worker policing ensures that the offspring of the queen will predominate in the group.
 In certain species of bees, ants and wasps, workers or the queen may also act aggressively towards fertile workers.
 Worker policing has been suggested as a form of coercion to promote the evolution of altruistic behavior in eusocial insect societies.
"I Love to Laugh", also called "We Love to Laugh", is a song from Walt Disney's film "Mary Poppins".
 It was composed by Richard M. Sherman and Robert B. Sherman.
 The song is sung in the film by "Uncle Albert" (Ed Wynn), and "Bert" (Dick Van Dyke) as they levitate uncontrollably toward the ceiling, eventually joined by Mary Poppins (Julie Andrews) herself.
 The premise of the scene, that laughter and happiness cause Uncle Albert (and like-minded visitors) to float into the air, can be seen as a metaphor for the way laughter can "lighten" a mood.
 (Compare Peter Pan's flight power, which is also powered by happy thoughts.)
 Conversely, thinking of something sad literally brings Albert and his visitors "down to earth" again.
 The song states a case strongly in favor of laughter, even if Mary Poppins appears to disapprove of Uncle Albert's behavior, especially since it not only complicates the task of getting Albert down, but the infectious mood sends Bert and the Banks children into the air as well.
Crab mentality, sometimes referred to as crabs in the bucket (also barrel, basket or pot), is a way of thinking best described by the phrase, "if I can't have it, neither can you."
 The metaphor refers to a common pattern of behavior seen in a group crabs when they are trapped in a bucket; their focus on saving oneself rather than willing to cooperate to save the entire group.
 Individually, any given healthy crab could easily escape from the bucket, but when grouped with others any individual's escape will be hindered by others.
 They will grab at each other in a futile "king of the hill" fight for survival which eventually ensures their collective demise.
Mud ring feeding (or mud plume fishing) is a cooperative feeding behavior seen in bottlenose dolphins on the lower Atlantic coast of Florida, United States.
 Dolphins use this hunting technique to forage and trap fish.
 A single dolphin will swim in a circle around a group of fish, swiftly moving his tail along the sand to create a plume.
 This creates a temporary net around the fish and they become disoriented.
 The fish begin jumping above the surface, so the dolphins can lunge through the plume and catch the fish.
The Cho Doo Soon Case is an incident that took place in December 2008, in which an eight-year-old girl (alias Nayoung) was on her way to school when she was kidnapped by 57-year-old Cho Doo Soon, who was drunk at the time.
 Cho raped and beat Nayoung at a public squat toilet.
 Nayoung had injuries to her internal organs, and was taken to a hospital, surviving the incident.
 Cho was arrested and eventually sentenced to twelve years in prison.
 The case sparked outrage and protest including Nayoung's parents and many others.
 In 2011, R&B singer ALi released a song based on Nayoung's story, titled "Nayoungee."
 The song attracted controversy after being widely criticized, and ALi chose to omit it from her upcoming album.
 She also subsequently issued an apology.
 She then went on to say that the song was also about her battle with being raped.
 The 2013 film "Hope" is based on this case.
Finite Automata is an American dark electronic and electro industrial music group originally formed in Pensacola, Florida in 2006.
 They have been based out of Atlanta, Georgia since 2013 and currently consist of vocalist, producer, and lyricist Mod Eschar, keyboardist Scott Storey, and instrumentalist Timothy Miller.
 They are known for their deep layered sound, frequent experimental live use of sound making devices such as radios and tapedecks, and their highly politically charged, confrontational, and theatrical stage performances.
 The group's name stems from the computer science concept of Finite State Machines, used as a metaphor for the predictability of human behavior.
 The band cites 1980s and 1990s electro-industrial groups Skinny Puppy, Front Line Assembly, and Project Pitchfork as their primary influences.
 Much of their early work has been referred to as a "throwback" as much of its style is reminiscent of early electro-industrial as opposed to the more recent and popular Aggrotech offshoot.
 Their more recent work draws heavily on industrial rock and the darker and more experimental sounds of second and third generation industrial like with previous releases, but with a healthy dose of modern production stylings and a more updated sound.
"Crabbuckit" is a single by Canadian hip hop musician k-os, released in 2004 as the first single from his album "Joyful Rebellion", and is the fourth track on the album.
 The title and work refers to the crab in the bucket syndrome where a group of crabs will pull down any crab that tries to escape, thereby ensuring their collective demise.
"In the Middle" is a song by English girl group Sugababes, released on 22 March 2004 as the third single from their third studio album, "Three" (2003).
 The Sugababes were inspired to compose the song based upon the different situations experienced on a night out; they wrote it in collaboration with Miranda Cooper, Brian Higgins, Niara Scarlett, Shawn Lee, Lisa Cowling, Andre Tegler, Phil Fuldner and Michael Bellina.
 Higgins, Xenomania and Jeremy Wheatley produced the song.
 "In the Middle" is a dance-pop, R&B and funk-influenced record that contains a sample of German DJ Moguai's song "U Know Y".
"Bless Me Indeed (Jabez's Song)" (sometimes called "Bless Me Indeed") is a song by Christian rock band MercyMe.
 Written by the band and produced by Pete Kipley, it was released as the lead single from the band's 2001 album "Almost There".
 The song was written at the request of the band's record label, who wanted to produce a song based on the popular book "The Prayer of Jabez" (2000).
 Although the band did not want to write it at first, they eventually relented and recorded it.
Charlie Victor Romeo is a 1999 play, and later a 2013 movie based on the play, whose script consists of almost-verbatim transcripts from six real aviation accidents and incidents.
 "Charlie Victor Romeo," or CVR, derived from the NATO phonetic alphabet, is aviation lingo for cockpit voice recorder.
 The play is a case study in crew resource management; a PBS special described several parallels between the behavior seen in these disasters and in emergency room situations.

Question: Who released a song based on a metaphor rephgering to the pattern of behavior seen in a group of crabs trapped in a bucket?
Answer: k-os
