Jam Factory (Korean: 잼 팩토리; RR: Jaem Paektori) is a South Korean music publisher which sources song tunes and lyrics for K-pop, J-pop and Mandopop artists from songwriters predominantly based in the US. Writers of the tunes are often songwriters for American companies, such as Brandon Fraley, a well known provider of tunes to South Korean girl and boy bands, who is a songwriter for Sony Music Publishing in Los Angeles. Korean, Japanese and Chinese language lyrics are usually provided by Jam Factory's own lyricists based in Seoul.
