The working title for U2’s new album is “10 Reasons to Exist.” 

Lead singer Bono revealed the moniker, perhaps jokingly,  in a radio interview after Christmas, according to The Independent newspaper.

There’s no release date yet for the group’s 13th studio album, which the band worked on throughout 2012.  Bono added, “Within the band, we’ve been calling it ‘10 Reasons to Exist,’ —but I will tell you we might have at least six of them.” Call us crazy, but we're betting that this will not be the final title, but it's a fascinating idea for a concept album.

U2’s last studio album was 2009’s “No Line On The Horizon.”
