Bola in this context is a very informal slang term, short for "dar bola", which means to pay attention, care, or worry about something. It's a common expression in Brazilian Portuguese.
In the song, the line "não bola com essas mensagens" translates to "don't worry about these messages". It's an interesting word choice because it's a colloquialism that might not be immediately obvious to learners, offering a glimpse into everyday spoken Portuguese.
Ever been caught texting an ex? That's exactly where this song starts! The singer is trying to calm down his current partner, saying, "Love, don't worry about these messages / I swear it was the last time." He admits he sometimes misses his ex, but quickly reveals his true feelings. He says if he ever feels nostalgic for the past, his heart will "scream for freedom."
This idea of freedom is the core of the song. In the chorus, he drops a bombshell, declaring, "You know I don't belong to anyone." He makes it clear that he's not interested in a committed, monogamous relationship. Instead, he sees himself as available to everyone, even cheekily suggesting he's there for both his partner and her friend. It's a bold and unapologetic anthem about wanting romantic freedom and casual fun without being tied down.
