U2 have dealt with some backlash following the release of their newest album, Songs of Innocence, which suddenly appeared in the music libraries of millions of iTunes users last week whether they wanted it or not. Apple also received some flak (and questions about their judgement) after it was revealed that the tech giant had paid the band $100 million for the opportunity to force the LP on its customers.

Now it looks like the controversial Songs of Innocence release was only the beginning of a new partnership between U2 and Apple. According to TIME, the Irish rock icons have teamed up with the company on a “secret project” that Bono hopes “will prove so irresistibly exciting to music fans that it will tempt them again into buying music—whole albums as well as individual tracks.”

The TIME article is short on details about the project, though the magazine has confirmed that it will involve a new digital format. We can only speculate what that entails, though its fair to say that convincing fans of music piracy and free streaming services like Spotify and YouTube to start paying for recorded music again, if they ever did in the first place, will be a monumental challenge.
