It was written by Lavigne and The Matrix (Scott Spock, Lauren Christy, and Graham Edwards), and produced by The Matrix.  The single reached number one in Australia (for six weeks), New Zealand and Mexico (for nine weeks), number two on the "Billboard" Hot 100, behind "Hot in Herre" by Nelly and number three in the United Kingdom.  Based on its chart performance, the song is Lavigne's second most successful single (only behind her 2007 single "Girlfriend") and was one of the most successful releases of 2002 with sales of over 3 million copies sold worldwide.  Lavigne broke a record set by Natalie Imbruglia's "Torn" when "Complicated" held the number one spot on the Adult Top 40 chart for 16 weeks in a row.  "Complicated" was nominated for two Grammy Awards for Song of the Year and Best Female Pop Vocal Performance. "Treat Her Right" is a soul music song, with a standard twelve-bar-blues structure.

Get the Knack is the debut album by the Knack, released in June 1979.
