It is the opening song and single from their second studio album Tiempo, and was written by eminent producer, director and composer Cris Morena.
"Tiempo" was the opening theme of the television series Rebelde Way during the second season, and was performed by Erreway in its final episode.
It is considered to be the most successful single of Erreway and as one of their signature songs, along with "Para Cosas Buenas" and "Memoria", reaching number one throughout Latin America, Europe and Israel.
It was also performed by Erreway members Manuel Aguirre (Felipe Colombo), Pablo Bustamante (Benjamín Rojas), Marizza Andrade (Camila Bordonaba) and Mía Colucci (Luisana Lopilato) in the final Rebelde Way episode.
The band performs the song and is heard by corpses, played by Rebelde Way cast members, and they rise from their greaves, desiring a new start.
