I didn't like it at first either, but now I think it's unique and catchy. It takes getting used to for sure, but he sounds great on the two new songs.
I actually used to love his voice. I didn't listen to DYKWYA for a few years, and when re-listening, his voice was sort of hard to take. It didn't make the album unlistenable, it's far too good for that, but my love for it definitely diminished a little.
Joy Division (my avatar is from "Control", as well).
