Now that is weird. Why does it annoy you if someone decides to take a different path? They are artists who make music as they see fit. Should they just stick to doing the same old thing over and over again because that's the way you like it? Should they not be true to themselves and just please totally random people who liked the style they use to make the music? Perhaps they have grown and thought they'd do something else for a change.
I have only heard 1987 and it's a magnificent tune and can't wait to hear the rest of the album because I am a MUSIC dude and openminded with it, good music is good music no matter the genre
