Sozinho is a Brazilian MPB/pop song written by Peninha, released in 1997. It became widely known after Sandra de Sá’s early interpretation and was later popularized by Caetano Veloso, who recorded it for the 1998 album Prenda Minha and also performed it on the live release Caetano Veloso e Bethânia Ao Vivo (1998). The lyrics speak of loneliness and longing in a relationship, with a speaker who wants closeness but resists ownership, wondering where the partner is and whether love is real. The track won the 1997 Prêmio Sharp for Best Music for Peninha, and Veloso’s version won Música do Ano at the 1999 Melhores do Ano. It also gained exposure by being used in the 1999 telenovela Suave Veneno, helping it reach a wider audience. Sozinho is a notable MPB tune in Caetano Veloso’s repertoire and in Brazilian pop music history.
