I think it gets an 8 out of 10 from me.
This album is a grower - the more I listen to it, the more I like it! There is always something else to take notice off with each listen.
I have one small criticism and that's the track sequence - This Is Where You Can Find Me Now - should be the second song. Other than that, it's great.
The stand-out songs for me are: Volcano, Iris, Cedarwood Road, Sleep Like a Baby Tonight and The Troubles.
Songs of Innocence has to be now in my top five U2 albums - in my opinion, it's the best they've released since Pop, maybe even Achtung Baby.
