The lyrics to Banda Uó's song "Não Quero Saber" speak about heartbreak and the difficulty of moving on after a relationship has ended. The singer is still longing for their former lover, even though they know their love is dead and they've been betrayed. In the opening lines, "ai que uó" is an expression of frustration or disappointment, and it's followed by the phrase "é o eletrobrega a sensação," which refers to the genre of music Banda Uó plays: a fusion of electronic music and regional Brazilian styles like brega and funk.

The song takes place in October, when it's raining outside and the singer is feeling the weight of their emotions. They admit to calling their ex-lover even though they can't afford it ("te ligando a cobrar"), and everything around them reminds them of what they've lost. They repeat the chorus several times, saying that they only want their ex-lover close to them and that they don't want to cry over anyone else. However, they also acknowledge that they don't know what to do to forget their past love, and that their heart is broken ("ai que dor").

The second verse reveals that the singer believes they were betrayed by their ex-lover, which is likely the cause of the breakup. They say that they don't want to know anything more about what happened ("não quero saber"), and that they're feeling lost and unable to love again. The song ends with another repetition of the chorus, the phrase "é o eletrobrega sensação," and the words "te ligo a cobrar" once again.

Overall, "Não Quero Saber" is a melancholic song that captures the pain of heartbreak and the difficulty of moving on. Despite the upbeat music, the lyrics are tinged with sadness and longing, and they reveal a deep emotional attachment that the singer is struggling to let go of.
