Hulk Rules includes songs in the genres of rock, pop, rap and other genres.
The song "American Made" was used as Hogan's theme song in World Championship Wrestling when he wasn't fronting the nWo. According to Hogan, "Hulkster in Heaven" was written in 1992 in honor of a Make-A-Wish Kid whom Hogan had invited to sit ringside at a show in the UK. When Hulk went out to wrestle, he saw that the seat was empty. Later, he was informed that the young hulkamaniac had died before the match had begun. The lyric "Guess there'll be an empty seat when I wrestle at Wembley," was direct result of the situation, despite the fact that Hogan has never wrestled at Wembley Stadium, and had not wrestled at Wembley Arena yet at that point (although he would eventually wrestle at the arena in September 1994 for WCW) Proceeds from the album went to help the young hulkamaniac's family, who was having trouble paying the medical bills.
That night, Hogan and Jimmy Hart wrote several songs for the album. Hogan let his wife Linda sing back up vocals on a couple of the songs because, according to him, she sounded better than "the rest of the stuff."
