Cover art for Get Up lyrics by Sleater-Kinney

To me this song is about emracing life as well as death (let it all go at once) and not dreading the latter (her soul is singing from every branch). "Like beggars, like Stars, like whores, us all" --> we're all going to die no matter who you were.

Could "Get Up" mean get up to heaven?

Anyway, great song, great band.
