premise: "Ryde or Die, Bitch", also known by its clean title, "Ryde or Die, Chick" was the lead single released from The LOX's second album, "We Are the Streets". The song was produced by Timbaland and featured him and Eve. It was the most successful single from the album, peaking at 73 on the "Billboard" Hot 100, 27 on the Hot R&B/Hip-Hop Songs and 22 on the Hot Rap Singles.
hypothesis: Timbaland has been known to sing duets.
reason: It is definitely correct because Timbaland and Eve had to record one duet: Ryde or Die, Bitch. To make the clean edit, they had to sing together at least one more time; therefore, Timbaland has definitely been known to sing duets. I'm not sure why the system missed this one. I really expected it to catch it.
