I'll repost here what I said last night in the hard rock thread :
I decided to listen to A Different Kind of Truth on my travels today - I redid my VH mp3 CD for the car right after I got the mp3s of this CD and just threw the whole thing on there since VH doesn't have so much material to where there wasn't room for all of it - and actually enjoyed most of it. I still think there are quite a few songs that are missing a vocal hook, but they have enough energy and rockingness to where they still didn't sound bad or anything. Granted, it's not classic VH is swimming in melodic glory or anything, but many of their songs have like one or two lines that are enough of a hook to where the rest of the song basically being one long rocking guitar solo works. Source of Infection from OU812 is a good example of this, since that song is basically one giant guitar solo, but the "Love is the source..of infection...woahhhh!!!!!!!!!!!" part is enough of a hook to make it work.
Back to ADKoT, I can say I like it a lot more than I did at first, or even 12 hours ago.
The back half of the album is much better than the front half. The best songs here are The Trouble with Never, Outta Space, Big River and Beats Workin'.
In light of that, I will promote it a bit in my list of VH studio album rankings:
1. Van Halen
2. 5150
3. Fair Warning
4. Balance
5. For Unlawful Carnal Knowledge
6. 1984
7. Women and Children First
8. A Different Kind of Truth
9. III
10. OU812
11. II
12. Diver Down
