Thers put this on a mix CD the other day, and I admit, I'm kinda sorta obsessed with it. This is Beulah doing "Silver Lining" (2001).
What I like about this is the more or less perfect blend of pop and punk, which I take to be the distinguishing characteristic of powerpop. Plus, there are moments, like the tail end of the guitar solo, which could have been written by any number of bitchin' bands, but (I confess) remind me most of Neil Innes writing for the Rutles. And that's just cool.
