Imagine you’re in a world famous rock band and your much anticipated, brand new album leaks onto the Internet a week before its launch. Who are you going to blame? Pirates? Internet companies? Nope. Try, your own record label. That’s what’s happening to U2 with its new album “No Line on the Horizon.” It seems that Universal Music mistakenly put it up for sale on an Australian website. It was only up for a brief time, but one copy is all it took. The album is everywhere. Sorry U2.
