"Complicated" is Avril Lavigne's first single, released in 2002 from her debut album, Let Go. The single reached number two on the Billboard Hot 100, becoming Lavigne's first top-ten single. The single also reached number three in the United Kingdom and number one in Australia and Mexico.
Complicated is the second album by American singer Nivea, released in the United States on May 5, 2005 (see 2005 in music) on Jive Records. It was primarily produced by her husband The Dream, with additional production from Lil' Jon, R. Kelly, Bryan Michael Cox and Jermaine Dupri.
After seemingly countless years with longtime producer Jerry Crutchfield, Tanya Tucker started anew with producer Gregg Brown on Complicated. It was an improvement over the disappointing previous Fire to Fire, yet only had one track hit the Top Ten in the Billboard Top Country Singles charts, the #9 "Little Things." "Ridin' Out the Heartache" was the only other single to chart at #45.
