I (obviously) love that cover XD I know what you mean, I listened to That Girl's a Straight-Up Hustler for the first time and was like, who the hell is this? I think he got a bit of a "growl" (not major) in some of the songs on Dirty Work which was pretty awesome.
I was definitely torn on that one. Listening to the progression of Alex's voice is really fascinating to me, too, ha. Running from Lions is excellent! Lullabies was the first I'd ever heard from them, too, and I fell in love with that song. Ahh, anything they do is good haha.
It's a fantastic album, haha. No matter which one I picked by them, it'd be number one because they're my favorite band ever XD haha. Especially with Remembering Sunday and all <3
