Olivia Rodrigo's remarkable music career has been shaped by two entertainment behemoths from the United States. Rodrigo's first showbiz gig was with Disney, where she made her acting debut on a children's television show in 2016. The other one is Taylor Swift, a major source of inspiration for the young Californian singer. Swift is also credited with authoring two songs on Rodrigo's debut album, "Sour," which effectively combine interpolations of Swift's own songs.
