Astyanax NASA isn’t having anything to do with foreigners sending superfluous radio beams towards their stuff.
That’s right. But as it says in the NPR article above, the music is being transmitted “in the direction of Voyager 1,” basically just a symbolic kind of thing.
If the transmission is not of the proper modulation type and format, Voyager 1 will just see it as some elevated background noise from the direction of Earth. 😉
