2. Songs of Innocence. U2. This is the 38th year that the band are working on new music. I’m afraid many of the critics are rather lukewarm about their concept to music in this album but that is really nothing more than disagreeing with commercialization. Its a global phenomenon U2 and they are bent on continuing it, so you would be well-advised not to stand in the way of it, because good music only comes upon you once every fine blue moon.
