The Voyager Golden Record is an attempt to do this. It's a record that contains sounds and images to portray life on earth [1].

This is a present from a small, distant world, a token of our sounds, our science, our images, our music, our thoughts and our feelings. We are attempting to survive our time so we may live into yours - President Jimmy Carter

a song i composed is being sent to the moon on an SD card or flash drive of some sort, i was told. Realistically if there is some faster-than-light mechanism, any interested alien or human could just "fast forward" and "rewind" through time to listen/watch our broadcasts from the appropriate distance from the original location.

Barring that, I'm guessing the equivalent of stone tablets, or the golden record are the best bet. I wouldn't place any bets on anything that requires magnetism or electricity to survive in open space for long enough to matter. Like, platter bit-flips due to radiation from outer space are a thing, and current leakage would eventually render something like SSDs unreadable.

So hard copy for earth, radio and hard copy for the universe?

How is that going to repair anyone's kettle?

It may help if the kettle is somewhere between the Earth and Mars :)
