There are two main types of narcocorridos: commercial corridos and private corridos. Commercial narcocorridos recorded made by famous artists who idolize a certain drug dealer and release a song about him, while private narcocorridos are usually commissioned by the drug dealer himself. While commercial corridos are available to the public, private narcocorridos are restricted to night-clubs that are frequently attended by drug dealers, or through CDs bought on the street. Drug lords often pay singers to write songs about them, as a way to send a message to rivals. These songs are found to be most popular on YouTube, many that have a banner "Approved by the cartel". These type of corridos are changing from the formula historic and typical corridos would usually take. A first person voice is now being sung instead of the historic third person point of view.
