I absolutely loved Blackbird all the way through. Grabbed me straight away from the first listen. I've listened to ABIII a few times now, and something just seems off about it.
I keep thinking that there are parts that are "wrong" melodically, but they aren't. I don't know exactly what it is, but I find it hard to enjoy the album. It's by no means a bad album, but it's not one that reeled me in and makes me want to come back to it again and again.
