Or you could just sell it as an online download for $3.50, you don't even have to do anything except pay a few dollars a month for server upkeep and people probably wouldn't pirate it coz it's cheap and well worth the money.

That's the concept behind iTunes.
Except you don't "own" a physical copy of the media, just the right to hear it via iTunes.
