Second hand digital music files

ReDigi offers an internet-era version of that stand-by for lean weeks, flogging off your records. It has a service which checks that you've deleted your copy of song, allowing it to sell it to a new owner.
Naturally, the RIAA feels this must be stopped, as ars technica reports:

ReDigi must "quarantine any copies on its servers of our Member's sound recordings so that those recordings are not exploited in any manner," the RIAA's Jennifer L. Pariser insists. On top of that, ReDigi must erase from its website "all references to the names and likenessess of artists signed to RIAA members" and break any ongoing connections between the operation's current downloaders and its servers.

Next, RIAA wants ReDigi to fork over "an accounting of all sales achieved and revenue generated" from RIAA member sound recordings through the ReDigi service, "so that we can discuss a resolution of our Members' claims."

"In this record, I note that the statutory damages for willful copyright infringement can be as high as $150,000 per work infringed," Pariser adds.

The main worry for the RIAA is that this again reinforces the idea of digital music being something you own, rather than rent; ReDigi maintain that it's perfectly legal to sell something you own, providing you do actually sell it.

That there's a demand for the saving offered by second-hand files - about 50% off the price - should be of more interest to the labels, as it suggests there's a huge market being missed out because the pricepoint is wrong. Maybe if they could stop being fixated on copyright, the RIAA could start to understand what happened to its business.
