Cargnello was originally associated with the punk rock band The Vendettas, which recorded two EPs in the late 1990s before releasing the full-length album It's Happening to You! in 2000. Cargnello then released his first solo album Lightweight Romeo in 2002. In 2004 he released his second album Between Evils, and the Vendettas reunited for their second and final album, Say No to the Vendettas. In 2005, he performed a live show at Montreal's Le Va-et-vient live music club, which was released as the album Live au Va-et-vient.
In 2007, he released his first French-language album, Brûler le jour. Although fluently bilingual as a speaker he was not experienced in French songwriting, so the album also marked his first time collaborating with other songwriters, including Jim Corcoran, Vincent Vallières, Ève Cournoyer and Fred Fortin. The album's lead single, "Une rose noire", became his first charting hit on Canada's francophone pop charts, reaching number 12 in the Quebec charts in 2007. Later that year, he was a finalist for Prix Félix-Leclerc de la chanson.
His second French-language album, Bras coupé, was released in 2009. He was a shortlisted nominee for the 2009 Echo Songwriting Prize in the francophone category for the album's title track, and for Francophone Songwriter of the Year at the 5th Canadian Folk Music Awards. He followed up in 2010 with the album La Course des loups and the limited edition EP La Reine contre Paul Cargnello, and in 2012 with the album Papa Paul. Papa Paul also included two songs in Haitian Creole, and included his second charting hit "L'effet que tu me fais".
He released his 10th studio album The Hardest Part Is You May Never Know with Union Label Group in 2014. It was his first primarily English-language album since Bragging, although it still featured two songs in French.
In April 2017, Cargnello released a kids' album for parents “tired of the schlock that the music industry throws at our children.” The album, titled Something Dimferent featured vocals by both Paul and his son Declan, and was released online only, including a full-length animated video available on Youtube.
In December 2017, a new album was released featuring the music of Paul Cargnello and the lyrics of street poet Siou Deslongchamps entitled Intense Cité. It was released in collaboration with the magazine L'Itinéraire. Profits from the album have gone towards the fight against poverty in Montreal.
MTL RnB is a bilingual musical project conceived by Paul Cargnello, released digitally in May, 2018. This album features his compositions and collaborations with singers and musicians from Montréal. 
In addition to his music, Cargnello has published two collections of poetry, Driving in Reverse (1997) and Old Hat (2002).
