It's one thing to have five people in the band who can sing, but it's harder than you'd think to get the most out of them.
This song has about four seconds' worth of feedback before we get the recurring guitar motif, which is 1) loud and 2) bounces up and down melodically, so it feels like the song starts by winding a clockwork mechanism, then kicking you in the seat of your pants. Only instead of falling over, you bounce from one wall to the next. This song sounds like a roller coaster looks, if you're not terrified of heights. It's jarring and aggressive (but, like, playfully aggressive; it's like being menaced with a turkey leg or something) to start, and the chorus locks into a groove. Like, you can feel the gears shifting from the wobbly silliness of the verses to the chorus, which chugs along.
I don't really know what else to say, other than few songs on this list are more fun, and none sounds more like being tossed into a swimming pool.
