U2's 13th studio album, "Songs of Innocence," is an album released a full 5 1/2 years after the commercial and critical disappointment of "No Line on the Horizon" with a list of producers as long as a Beyonce album. To that long gestation period Bono said, "Rumor has it we haven't made a U2 album in the last five years. We have. We've made several. We just didn't release them because we were waiting for something that would be as good as the best we've ever done." But, once the album was released, it wasn't the music that everyone was talking about, but rather how it was released. Which is a shame because, while it may not be the experimental classic of Achtung Baby, it is wildly underrated containing some of the most personal songs of U2's career. The question is, will its virtues ever overshadow the controversy known as Apple-Gate.
