"Lit Up" is the debut single by American hard rock band Buckcherry, taken from their self-titled debut album. It was the band's first and only number one song on the Billboard Mainstream Rock Tracks chart.
The song reached number one on the Billboard Mainstream Rock Tracks chart for three weeks and number 33 on the Modern Rock Tracks in mid-1999. It was ranked number 98 on VH1's list of the 100 Greatest Hard Rock Songs in January 2009.
The music video for the song features the band playing in front of an audience. MTV censored the lines glorifying cocaine.
