"Mais Uma Vez" is a song composed and sung by Brazilian musicians Renato Russo and Flávio Venturini in 1986.
In 1986, Flávio Venturini was getting to know Renato Russo at EMI-Odeon studios in Rio de Janeiro, when 14 Bis and Legião Urbana were in rooms close to each other recording their next albums (respectively, Sete and Dois).
Venturini invited Russo to join the song recording with 14 Bis, which resulted in Sete's final version.
The lyrics feature several motivational sentences like "espera que o sol já vem" ("wait because the sun is about to come"), "nunca deixe que lhe digam que não vale a pena acreditar no sonho que se tem" ("never let people tell you it's not worth it to believe in your dreams"), and "se você quiser alguém em quem confiar, confie em si mesmo" ("if you want someone to trust, trust yourself").
