“Yo Quería” is a Spanish adaption (D.A.R.) of the song “Io Vorrei” from Italian singers Sandro Giacobbe and Toto Cutugno. Both recorded and performed “Io Vorrei,” after co-writing the song together in their albums “Io Vorrei” and “Toto Cutugno” (respectively) from 1990.
In Crisitan Castros' album “Azul” booklet, the song is credited to both Italian artists (Toto Cutugno / Giacobbe).
The only difference is that Sandro Giacobbe released the song as a single [https://www.discogs.com/release/1985251-Sandro-Giacobbe-Io-Vorrei], while Toto Cutugno did not.
