premise: Titus is the original soundtrack to the 1999 motion picture "Titus". Elliot Goldenthal wrote the score for the film, an adaptation of Shakespeare's first, and bloodiest, tragedy "Titus Andronicus"; written and directed by Julie Taymor, Goldenthal's long-time friend and partner. The only non-Goldenthal piece is an old Italian song called ""Vivere"" performed by Italian singer Carlo Buti.
hypothesis: Vivere is the only piece on the Titus soundtrack performed by Carlo Buti
reason: While it is stated that all the other pieces were composed by Goldenthal, it is not stated who performed them so it could be Carlo Buti. I think the system got it wrong because the statement seems like a logical assumption
