Manhas is an interesting word that can mean 'tricks', 'skills', or 'the knack' for doing something. It implies a certain cleverness or expertise.
In "Quem Tem o Dom," the lyrics state, "Tem, tem gente que tenta, mas não tem as manhas pra fazer tão bem" (There are people who try, but they don't have the knack to do it so well). Here, it refers to the unique skill or special touch that the artists possess, making them stand out from others.
"Quem Tem O Dom" is a boastful, funky party anthem built around a pun. In Portuguese, "dom" means "gift" or "talent," and the singer keeps repeating it as a playful, percussive "dom, dom, dom" hook, half word and half drumbeat.
The lyrics are pure swagger. The singer claims he has a natural gift that other people try to fake but can't pull off. He brags that he's the original, that nobody on the market can copy him, and that his charm ("a dose of my kiss") is enough to win anyone over. The chorus dares the DJ to "bring on the bass" so the crowd can feel the beat drop.
It's a lighthearted, self-confident dance track made for a party, not a deep story. The joke is that "having the dom" (the gift) really just means having the moves to make everyone dance.
