Total Request Live (known commonly as simply TRL) is a television series on MTV that features popular music videos. TRL is MTV's prime outlet for music videos. In addition to music videos, TRL features daily guests. The show is a popular promotion tool used by musicians, actors, and other celebrities to promote their newest works to the show's target teen demographic. TRL returned on October 2, 2017. The revived iteration has since swapped the iconic daily countdown with a weekly top five with special guests adding their favorite songs to the official TRL playlist, ranked by viewers via social media, played during the show.
