Trena Steward and Lorenzo Pryor allege West used part of their father's 1974 song "Bumpin' Bus Stop?" in his 2005 hit "Gold Digger," TMZ reported Monday.
Steward and Pryor have asked a judge to stop the sale of West's 8-year-old record. They also are seeking unspecified damages, the celebrity news website said.
