Back in 2011, a company called ReDigi attempted to give consumers just such a pipe dream. The idea was to take advantage of the “first sale” doctrine, which gives those who purchase copies of copyrighted work the right to sell, display or otherwise dispose of that particular copy notwithstanding the interests of the copyright holder. ReDigi provided cloud storage and a market for “used” songs bought off of iTunes. Naturally, the record industry wasn’t happy, which led to a lawsuit and a big ruling in April 2013.
