It's not even that it's un-VH. It just plain sucks straight out.
Yeah, I recall that it is a very rough and jarring listen. I don't like the Hagar era songs or albums, but I don't find the songs completely unlistenable like I do with respect to the tracks on VH3. I absolutely can't stand Gary's (or Ed's on How Many Say I) singing on the album either. I have revisited it a few times over the years, but it has only strengthened my initial opinion. Fortunately, I never purchased this album.
Crazy to think Van Halen only released one studio album after VH3 along with a couple of additional Van Hagar tracks. I do still enjoy "A Different Kind of Truth," so I'm happy we got something along with a few tours with DLR. It just could have been so much more. Then again, maybe that was all this crew was capable of producing post VH3 when you consider how dysfunctional they appeared to be.
