"You Should Be Mine (Don't Waste Your Time)" is a song by American singer Brian McKnight, released by Mercury Records on August 19, 1997 as the first single from his third studio album, Anytime (1997).

It was co-written by all three, while production—based on a sample of James Brown's 1972 song "I Got Ants in My Pants"—was handled by Mase's colleagues at Bad Boy Records, including the label's founder Puff Daddy, as well as its in-house producers Stevie J and Ron "Amen-Ra" Lawrence.
"You Should Be Mine (Don't Waste Your Time" peaked at number 17 on the Billboard Hot 100 and number four on the Hot R&B/Hip Hop Songs chart. It landed at numbers 86 and 35 for the charts' respective year-end lists.[2] It sold at least 600,000 copies by the end of the year.[3]
