Yes fair point. I surprised myself giving it an 8 and here's my thought process.
I'd only heard the one song before and liked it without feeling I ever had to hear it again. When I heard the first three songs, I though, right, this is 5-6 territory - nice enough but, like you said nothing like the best in the genre.
But what followed really surprised me - one minute I think I'm listening to the American version of Busted and then they roll out these slower more interesting songs with some nice jangly guitars plus harmony vocals. So now I'm thinking, I might give this a 7.
But that was before the last few songs, and I think most of us agree it's like listening to an Oasis tribute band. But to be fair, those songs are as good as a lot of the Oasis songs. Just to be clear, I like Oasis' first two (I mean three - thanks to BH for making me listen to The Masterplan) albums, but they are no way near my top 20. Oasis would probably just about make my top 50 artists. But on this album, "Bought for a Song", "Supercollider" and "Elevator Up" had me wanting to listen to them again.
The fullness of time might show I've been a bit giddy giving Fountains of Wayne an 8, but it's an absolute rock-solid 7 at worst. The fact that I didn't expect to like it so much really helped, which is where the additional point came from. Despite the fact that I try not to, I can't help but have pre-conceived notions about whether I'm going to like or dislike every single album that is nominated on here. I liked the Micheal Stearns album a lot more than I thought I would but conversely, the Drive-By Truckers should be right up my street, but I found Southern Rock Opera was way too long and didn't have enough great songs - yet I rated both those two albums a 7.
Relative scoring is a difficult balance but I've played Welcome Interstate Managers through three times and listened to a few more a fourth and fifth time. If that's not worth an 8 then I don't know what is. I think this is an unbelievably good pop album without qualifying for a 9 or 10.
