The version of “Check on It” used in the clip features a remix of “The Pink Panther Theme” and a verse-rap from American rapper Bun B. It was composed by Knowles, Swizz Beatz, Sean Garrett, Angela Beyincé and Slim Thug. Initially recorded by Knowles only, the song was supposed to be featured on the soundtrack album for 2006 film The Pink Panther, in which she co-stars.
“Check on It” is an R&B and hip hop song, which is instrumentally complete with a heavy bassline, strings, and wind instrument. Lyrically, it takes place in a club, where Knowles is letting the male patrons know that they are welcome to come and look at her sexually attractive body when she is dancing.
