Observando means "observing" or "watching". While it might seem common, its use in this song is particularly poignant and sets a different tone than the repeated "ya" (enough/already).
In the context of the lyrics, "Yo vengo observando que tú estás cambiando tu forma de ser" (I've been observing that you are changing your way of being), it highlights a period of quiet, painful realization before the final breakup. It's a more reflective and less confrontational word, adding depth to the narrative of a relationship ending.
The whole song hangs on one Spanish word. Ya means "already," "now" and "enough" at the same time, and Juan Gabriel uses it here as a door closing on someone who will not accept that the decision was made a while ago: "Ya no te quiero" (I don't love you anymore), "Ya tanto lloré / Que más no puedo" (I've cried so much that I can't cry anymore). By the chorus the word has stopped being a word and become a shove toward the door — "Ya, ya, ya, ya, ya vete" (Now, now, now, now, go). La India and Banda El Recodo turn what could be a private argument into a public one: every line he sings comes straight back at him as an echo, "(Vete, te lo pido)" (Go, I'm asking you), so he never gets the last word he keeps trying to take.
The reason arrives late and much quieter than the rest of it: "Desde hace mucho tiempo / Yo vengo observando / Que tú estás cambiando / Tu forma de ser" (For a long time I've been watching you change who you are). He isn't leaving over one fight — he watched it happen slowly and said nothing until now. That is why the last thing he asks for is time rather than an apology: "No pierdas el tiempo / Ni me lo hagas más perder" (Don't waste your time, and don't make me waste any more of mine). The brass answers at full volume, which is how a banda ends an argument.
