''Louder Now'' is the first major label release from Taking Back Sunday. The first single off the album is "MakeDamnSure". The song "Error Operator" has been released on the ''Fantastic Four'' 2005 film soundtrack, but has been revamped for ''Louder Now'', resulting in the 2005 version becoming known as the 'F4 Edit'. ''Louder Now'' was leaked onto the internet in its entirety on April 19, 2006.
Other countries' release dates are posted on the official Taking Back Sunday website. There were two other songs recorded during the ''Louder Now'' sessions, "Brooklyn (If You See Something, Say Something)" and "Sleep". "Brooklyn (If You See Something, Say Something)" is on the iTunes bonus version of ''Louder Now'', and "Sleep" is on the "MakeDamnSure" UK single released May 22.
The title ''Louder Now'' comes from the song "What's It Feel Like To Be A Ghost?", as well as "Bonus Mosh Pt. II" on their second album ''Where You Want To Be''.
Late 2006, a special edition CD/DVD was released entitled ''Louder Now: PartOne''.
The album was voted the best of 2006 in ''Kerrang!'' magazine's end of year poll.
As of June 9, 2008, the album has sold 900,000 copies, according to Nielsen SoundScan.
Louder Now was the band's last release featuring Fred Mascherino as guitarist and co-lead vocalist.
