Who doesn't love the first, the original "Symphony of Science" tune, "Carl Sagan - 'A Glorious Dawn' ft Stephen Hawking"?
This song was posted five years ago today! How time flies!
You can catch up on the full line of Symphony of Science tunes at the Melody Sheep YouTube channel.
In honor of the anniversary, John Boswell from MelodySheep (whom I interviewed a few years back right here at PsiVid) held a contest looking for the best fan remixes of tunes and has the selection available to listeners for free!
