U2's new Album, 'Songs of Innocence' was released at The Apple Event with CEO Tim Cook. What's different about it is that immediately it went free to every itunes customer (500m) immediately.
Which is the largest album release of all time. Obviously.
It's on Itunes Radio and Beats music too but I've tried to find it and frankly, can't. But it's there.
And it's one hell of a promotion!
(but pretty hackneyed launch if you ask me.....)
