U2's label behind album leak

U2's eagerly-awaited new album was leaked on the internet by the band's own record label, according to reports.

'No Line on the Horizon' isn't scheduled to hit stores until Friday, February 27.

But copies went onsale online this week, after it was released by Universal Music Group's Australian branch, reports Rolling Stone.

Fans were free to download and share the disc for several hours before the mistake was spotted and the tracks pulled.

U2 and Universal have yet to comment on the leak.
