He rose to prominence in the mid-1990s after making a string of major hits for artists such as the Backstreet Boys, Britney Spears, and NSYNC. Some of his earlier hits include "I Want It That Way" (1999), "...Baby One More Time," (1999) and "It's My Life" (2000).

Since 1999, Martin has written and co-written 21 Billboard Hot 100 number-one hits (most of which he has also produced or co-produced) in the United States, including Kelly Clarkson's "Since U Been Gone" (2004) and "Behind These Hazel Eyes" (2005), Katy Perry's "I Kissed a Girl" (2008), P!nk's "So What" (2008), Britney Spears's "Hold It Against Me" (2011), Maroon 5's "One More Night" (2012), and Taylor Swift's "We Are Never Ever Getting Back Together" (2012), "Shake It Off" (2014), "Blank Space" (2014), and "Bad Blood" (2015). Martin is the songwriter with the third-most number one singles on the chart, behind only Paul McCartney (32) and John Lennon (26).
