On their debut album released in 1986, the Beastie Boys told their fans to fight for their right to do what?

Released on their first album 'Licensed to Ill' in 1986, the American hip hop group, the Beastie Boys, told their fans "You gotta fight for your right to party." This is a lyric from their song 'Fight for Your Right', which they later released as a single with the title '(You Gotta) Fight for Your Right (To Party!)'.

The song was written by Adam Yauch (1964-2012), one of the founding members of the band. It was intended to make fun of similar over-the-top rock and hip-hop songs about partying, but this was lost on most listeners. Instead, their music engaged the exact audiences they were attempting to satirize. '(You Gotta) Fight for Your Right (To Party!)' reached number 7 on the 'US Billboard Hot 100' and 11 in the 'UK Singles' chart.

The Beastie Boys formed in 1981 as a punk rock band. They claimed the word 'Beastie' is the acronym of 'Boys Entering Anarchic States Towards Internal Excellence', but this was invented after they chose their name. 'Licensed To Ill' was their first album, and it is credited for inventing 'rap rock', a form of rapping combined with rock guitar music.
