Sei Lá (A Vida Tem Sempre Razão) is a Brazilian song written by Toquinho and Vinícius de Moraes and originally performed by Toquinho and Vinícius around 1971. It appears on the album Toquinho & Vinícius and is part of the MPB genre with Brazilian folk and samba influences. The lyrics ponder life’s questions, the cycle of birth and death, and the idea that life is a grand illusion yet has a reason, with the refrain Sei Lá Sei Lá underscoring that life has its own justification. The track has been issued in other versions, including a 1977 recording with Antonio Carlos Jobim and Miúcha, showing its enduring place in Brazilian music. The song marks a collaboration between two iconic Brazilian songwriters and performers and remains a hallmark of early 1970s MPB.
