If you’ve been listening to a leaked copy of U2’s “No Line on the Horizon”, then it’s possible that the RIAA know exactly who you are, if you believe Techcrunch who got all in a tizzy on Friday over the suggestion that Last.fm has been handing over listener data to the record company.

Last.fm immediately denied the accusations, saying:

I’d like to issue a full and categorical denial of this. We’ve never had any request for such data by anyone, and if we did we wouldn’t consent to it.

Of course we work with the major labels and provide them with broad statistics, as we would with any other label, but we’d never personally identify our users to a third party – that goes against everything we stand for.

The RIAA followed that up, with:

“[We’re] not sure where that rumor came from. It’s not true.”

So you’re probably safe for now, but given how much personal data many people share on Last.fm, if you’re one of the first with a copy of a leaked album, then you might want to be careful about scrobbling that fact. Just a thought.
