Personally, my favorite composition of Richie's is "Lady," which became a huge hit for Kenny Rogers. But "Three Times a Lady," released in 1978 when Richie was still a member of the Commodores, is a close second. It is a beautiful song, exquisitely arranged and sung by Richie. It still sounds good today, and I'm sure brings substantial royalties into the pocketbook of Mr. Richie - as it should.
"Three Times a Lady," Commodores, from the summer of 1978.
