Fool For You and Blue can go, however the rest of the album is pretty great.
Rearview, She and Drunk are the holy trinity - MKYL really came through on the latter, the production is sublime and superior to Pillowtalk.
Single wise She is probably the obvious choice, also TIO and possibly Wrong...
Like I Would is okay I guess, but I'm still waiting on Befour - that instrumental from the Fader video sounds less generic than his current songs.
His accent really comes through on his solo material. Maybe he was right when he claimed the 1D producers told him to sing in a different way.
