Peter Bjorn And John - breakin point, 2016

"The integration of whistling on the track was initially unintentional. Morén whistled the tune while recording the song at Ingrid Studios in Stockholm, and the recording ended up being kept for the final version. Morén explained they were originally reluctant to include the whistles as they felt it might be viewed as "so obvious" considering their breakthrough single "Young Folks" from Writer's Block (2006) was heavily built upon whistling.[4] As "Breakin' Point" was conceived near the ten-year anniversary of Writer's Block, Morén described the whistling aspects as a "nice tribute" to "Young Folks". The band preferred a tribute record over issuing a "big deluxe" re-release of Writer's Block or an anniversary tour. An "early version" of the song, sans the whistles and solely produced by the band, is included on the deluxe edition of the album."
