Personally I'd say IV
It's got to the point where I'm so sick of hearing those songs I don't think I've needed to play the album in years.
And it's not like I played it a great deal before that either. I always found it rather dull. It doesn't have the rawness of the first album, doesn't have the power of the 2nd, doesn't have the eclecticisms of the 3rd. It's just sort of.....there.
and to anyone voting Presence ... You have no taste.
