 Musically, it is a hip hop song, sampling a hook from LL Cool J's track "Jingling Baby", released in 1990.

"Bye Bye Baby" was the Finnish entry in the Eurovision Song Contest 1994, performed in Finnish (despite the English language title) by CatCat, a duo formed by two sisters, a blonde and a brunette, named Virpi and Katja Kätkä, whose family name is phonetically similar to "cat cat" in English (especially in plural: Kätkät).
 The song is sung from the perspective of a woman ending a relationship because of her lover's infidelity.
 She claims that "I won't cry when this ends" and seems generally positive about her future prospects.
 The Eurovision version of the song is almost entirely in Finnish, according to the Contest rules in force at that time, but the first line of the chorus (quoted in the song's title) is in English.
