Or you can listen and look at the entire contents of the record at the JPL website. And since the record was made for NASA, doing so violates no copyrights whatsoever.
I had forgotten, NASA used a bunch of copyrighted content for the record, so only some of it is available at the JPL website. Eternal copyright sucks. However, searching your favourite torrent site for “voyager golden record” will get you a CD rip of the record’s audio.
