It sounds to me, from reading the review, that you liked this album for the most part, you just didn't like the inconsistency of it all...and for that 67% seems a little low.
Well I couldn't exactly rate the lyrics, creativity, or lasting value high? I mean come on haha. To me they weren't high at all. I'd say I was rather generous with the ratings.
Plus I hate ratings, most of us staff do.
