Murmuró means "he/she/it murmured." It's an interesting word because it describes a low, indistinct sound, often associated with secrets or quiet conversations.
In the context of the song, it appears early on, setting a somewhat mysterious or intimate tone. It suggests that something is being said softly, perhaps something that isn't meant to be heard by everyone, adding a layer of intrigue to the lyrics.
Michel el Buenón's "No Molestar (En Vivo RD)" feels like a defiant anthem about living life on your own terms, without worrying about what others think. He sings, "para que hablen una vez / murmuró" [so they talk once / he murmured], suggesting he's well aware of gossip but chooses to ignore it. He's not interested in what might happen "dentro de un mes" [within a month] because it's "para nada" [for nothing]. It's all about living "sin pensar" [without thinking] too much about the future or others' opinions.
He declares, "yo soy merecedor" [I am worthy] and talks about finding a place "donde no nos busquen más" [where they won't look for us anymore]. The song seems to be about escaping the noise and focusing on what truly matters to him, even if it's just finding a "rinconcito" [little corner] to sleep. It's a call to enjoy life and share love, as he repeats "el amor / vamos a matar" [love / let's kill it] – not in a negative way, but more like embracing it fully and passionately, even "en las calles" [in the streets].
