God, this is hilarious. I'm not at all picking on you, LM, but rather pointing out how the word "grower," in listening-to-music terms, has changed so much and so rapidly, in the last year or two. I mean...I don't follow Spoon, these days, so I'm not really up to speed on all of this...didn't this leak, like, three days ago? That kills me! It's a grower...but it takes less than a week to blossom!
Not a Spoon issue, and I don't have an issue with your post (in fact, I know what you mean, if not in regards to this album). I just think that's brilliant, to be talking in these terms before an album even comes out. Once upon a time, White Light/White Heat and Red House Painters records were growers, and that was years after the fact. Now pop albums are growers because they sound better on second listen than first. Always tickles me.
