"That Ain't Right" is the 1942 debut single by The King Cole Trio. That Ain't Right" hit number one on Billboard magazine's Harlem Hit Parade chart for one week. Although the song was the King Cole Trio's first successful record, it would be their only release for Decca, as the contract with the company expired before "That Ain't Right" became a hit.
