The track was written by bassist/vocalist Gene Simmons and guitarist Vinnie Vincent, although some versions of the album mistakenly credit Paul Stanley and Vincent. The latter had been working with songwriter Adam Mitchell when he discovered that Mitchell had connections to Kiss, and Vincent made it a point to meet Simmons through Mitchell. After meeting and exchanging phone numbers with Simmons, the two got together and wrote "I Love It Loud" in addition to another song called "Killer", which appeared on the "Creatures" album during the same writing session.
