The vocal comes from Cuándo Volverás, a 2000 track by Aventura, the New York bachata group fronted by Anthony Santos, known professionally as Romeo Santos. The clip isolates his voice from the original recording, removing the guitars and percussion that define classic bachata. Short isolated vocals like this circulate widely on soundboards and in fan edits because they are easy to drop over a new scene without clashing with other music. Its brief, questioning tone keeps it useful for reaction and storytelling edits long after the song's original release.
