The app for independent voices
Dylan’s “Hard Rain” appears to have at least two voices: the opening refrain question that begins each verse addressed to “you” and then the question’s first-person answers. And the refrain lines that end each verse (“And it’s a hard,” etc.) could be thought of as being in third person.
In English, “you” can be pretty ambiguous: it can refer to the reader/listener, or to someone the speaker/singer is talking to in the poem/song, or the speaker/singer themself, or even as a less-affected substitute for “one.”
So in this song the “you” could be Dylan addressing himself (he has blue eyes, a detail he added to the “Lord Randall” questions used in the song) and then answering himself. Usually context makes it clear what “you” means, but maybe not in this case.
