Te lo Agradezco, Pero No

"Te Lo Agradezco, Pero No" is a song recorded by Spanish singer Alejandro Sanz and Colombian singer Shakira, for Sanz's eighth studio album El Tren de los Momentos (2006). It was released as the second single from the record in December 2006 by Warner Music Latina. The track was written by Sanz, while production was handled by him along with Lulo Pérez. "Te Lo Agradezco, Pero No" is the second duet recorded by the two singers, following "La Tortura" for Shakira's album Fijación Oral Vol. 1 (2005). The song came about after she approached Sanz, telling him that she wanted to collaborate on something different from her own material. 

The music video for "Te Lo Agradezco, Pero No," directed by Jaume de Laiguana, was filmed in Brooklyn in 2006 and released on January 11, 2007. It serves as a continuation of the video for Alejandro Sanz's previous single "A la Primera Persona" (2006). In "Te Lo Agradezco, Pero No," the dynamic between Sanz and his love interest shifts, with Sanz clarifying that "there are no promises that are worthy after everything is finished." At Shakira's request, this video marks the first time Sanz performs choreography. A behind-the-scenes clip of the music video was included in the DVD of El Tren de los Momentos: Edición Especial (2007). The video was also featured in Sanz's compilation album Colección Definitiva (2011). It was well-received and earned a nomination for Video of the Year at the Los Premios MTV Latinoamérica 2007, held on October 18, 2007.
