Toxic (song)

"Toxic" is a dance-pop song written by Bloodshy & Avant, Cathy Dennis, and Henrik Jonback for Britney Spears' fourth studio album In the Zone (2003). The song describes having an affair with a married man. It was released as the album's second single in early 2004 (see 2004 in music). "Toxic" enjoyed international success, topping many singles charts. The song was chosen as the second favorite song of the world (all time) in a global survey made by Sony Ericsson, in which 700,000 music fans of 66 countries contributed, behind "We Are the Champions" by Queen.

It has been covered by The BossHoss, Local H, the Chapin Sisters, Juliet Turner, Nickel Creek, Hurra Torpedo and Mark Ronson. Marillion played it during their Marillion Weekend in February 2007 in the Netherlands, and their performance was released (in audio only) on the DVD version of the single "Thankyou Whoever You Are / Most Toys" in June 2007. Monsters From Mars has released an instrumental surf version.
