According to Warren Zanes’ 2015 Tom Petty biography:
And Damn the Torpedoes was an album, with studied sequencing and interstitial material between song matter that connects the whole experience into one event. “Louisiana Rain,” “Even the Losers,” and “Century City” all have bits of audio scrap leading into the actual recordings, and some of those scraps would become as well loved as the songs themselves. Mike Campbell’s wife, Marcie, can be heard shouting, “It’s just the normal noises in here!” right in the middle of side one. It was something Petty found in a Campbell demo. “I had a TEAC four-track recorder, and it was right around the corner from the washing machine in our little rental house,” explains Campbell. “I was trying to record something, and the washing machine was broken, making this loud noise. I yelled at Marcy, ‘You have to turn that off!’ And she goes, ‘It’s just the normal noises in here!’ Like, ‘Shut the fuck up! I’m living my life!’ Next thing you know, we’d be in the car, and there was Marcie on the radio.” Petty pushed Iovine to get the audio snippets on the record. The producer didn’t want any of it. “Tom and Mike were Beatles freaks,” says Jimmy Iovine. “They wanted that stuff on there, not me. But, really, these guys were already brilliant record producers. The record’s perfect. It was number two to The Wall for nine weeks.
