In "No Hay Igual", Furtado sings in Spanish and raps in Portuguese over a reggaeton rhythm. The album also features more introspective songs, and "The Sunday Times" wrote that it "has a surprising sadness to it." The seventh track, "Te Busqué", which features Latin singer Juanes, is about Furtado's experiences with depression, which she said she has had periodically since she was around seventeen years old. Furtado said she was unsure what "Say It Right" is about, but that it encapsulates her feeling when she wrote it and "taps into this other sphere"; in an interview for "The Sunday Times", it was mentioned that it is about her breakup with DJ Jasper Gahunia, the father of her daughter. "In God's Hands", another song on the album, was also inspired by the end of their relationship. In April 2006, a remix of "No Hay Igual" featuring Calle 13 was issued as a club single in the US. During the same period, "Promiscuous" (featuring Timbaland) was released for digital download in North America. Promiscuous became Furtado's first single to top the US "Billboard" Hot 100 and was released in Australia, where it reached the top five. The lead single in Europe and Latin America, "Maneater", was released in late May to early June 2006. It became Furtado's first single to top the UK Singles Chart and made the top ten in other countries; it reached the top five in Germany and the top twenty in France and Latin America. The second single in Europe, "Promiscuous", was released in late August to early September 2006 but it did not perform as well as "Maneater". It peaked inside the top five in the UK and the top ten in other countries, including Germany, and it reached the top twenty in France. During the same period, "Maneater" began its run as the second single in North America; it was not as successful as "Promiscuous", reaching number twenty-two in Canada and the top twenty in the US, though it became a top five single on the ARIA Singles Chart. Releases of the third North American single, "Say It Right", and the third Europe single, "All Good Things (Come to an End)", took place in November and December, and the third Latin American single, "Promiscuous", was released in January 2007.
