Apple SVP of Internet Software & Services Eddy Cue told Billboard that more than 81 million customers ‘experienced songs’ from U2’s Songs of Innocence album either through plays or streams over iTunes, iTunes Radio, or Beats Music where the album was exclusively available to users. The Apple exec added that 26 million full downloads of the album were measured by Apple. Cue also shared that U2’s music had previously been purchased by 14 million customers through iTunes since 2003.

I call that a success for U2! I personally enjoyed the album.
