 The album was certified triple platinum in its home country, and triple platinum in Australia by the Australian Recording Industry Association (ARIA), as well as double platinum by CRIA in Canada.
 "Toxicity" produced singles for the title track, "Chop Suey!
", and "Aerials".
 The last of these peaked at number one on the "Billboard" Mainstream Rock Songs and Alternative Songs charts.
"Rebellion" is a song by American rock band Linkin Park.

Open House Party (most of the time, shortened to OHP) is an American radio show hosted on Saturday and Sunday nights by Kannon, who also hosts the afternoon drive slot on 102.9 Now.
 The show promotes itself as "the Biggest Party on the Planet".
 It focuses on playing contemporary hit radio (CHR) music, also known as Top 40.
 The show differentiates itself from most Top 40 because it plays a high rotation of remixes.
 Unlike most radio stations or programs, every song played on OHP is by a listener request, rather than computer systems automatically inserting songs that may not even be popular anyways.
 The show started in 1987, and was hosted by John Garabedian from September 1987 to January 2017.
 Garabedian created the show, and hosted both Saturday and Sunday nights for a long period of time.
 Open House Party is broadcast on more than 50 stations around the world.
It launched in December 2003 and distribution was limited to select cable companies.
 As of May 31, 2006, XY.tv has ceased operations, and is no longer broadcasting.
 It was wholly owned by American radio personality John Garabedian.
