The band hired the bass guitarist Lee Marcucci (from Radio Taxi) to play in their album Como Estao Voces? (How Are You?). As this album was released, the five remaining members continued to write the history of more than 20 years of the band. With self-help hits as "Enquanto Houver Sol", questions on relevance remain on Titas' side, which faced declining sales and the ageing of their fanbase.  In 2005, they released another MTV-branded album, only this time in a non-acoustic live performance. This album generated a new hit for the group, called "Vossa Excelencia", that basically criticizes the hypocrisy and lack of care from politicians, thus bringing the band back to its roots. It was seen as another opportunistic stunt by Brazilian critics, as the song was released exactly when Lula's government was facing manifold accusations of corruption.  On February 18, 2006, Titas opened the Rolling Stones free concert at Copacabana beach, Rio de Janeiro for an audience of some 1.5 million people.  In 2007, the band started a tour, entitled 25 Anos de Rock (25 Years of Rock), joining Os Paralamas do Sucesso to celebrate the 25th anniversary of both bands, as well as the 25th anniversary of the rising of 1980s Brazilian rock bands. The two line-ups played together most of the time on the shows, presenting also some invited musicians, like Arnaldo Antunes, Andreas Kisser and Dado Villa-Lobos. The concert in Rio de Janeiro, which took place at January 26, 2008, was recorded and filmed. The resulting CD and DVD from the show were released five months after.
