I didn't read the rest of this thread because I don't have the patience. I skimmed it and basically got that some people like it and some people don't. They played it safe vs they are evolving their sound... etc., etc., blah blah.
Here's my take on the first listen:
I'm not impressed.
There, I said it.
I'm not impressed.
"You always were my favorite drug, even when we used to take drugs."
Really? Sorry, that line just annoys the hell out of me.
People who know me, know that I am a huge fan of STP, and have been for years. I've been (not so much recently) a regular contributor to this website, and have defended the band on numerous occasions.
Maybe it's my musical tastes changing. Maybe it's just not a good album. I don't know. The sound changed, and it changed in a way that I don't much care for. I agree that bands should grow and evolve. But just because they grow and evolve, it doesn't mean that I have to grow and evolve with them, does it? They went in a direction that I didn't go in. I'll still listen to my old STP, and I'll still love this band. I just won't love this album.
...at least not right now.
