Pj Harvey – We Float chords

Bass theme (on piano) throughout:

D  D E F  -- through first verse
D  D E F (G accents) -- through second verse
D  D E F (D G accents) -- rest of the way

The G accents get more prominent after the first chorus.

"But now...

Chorus:
G5   Bbmaj7    F"Weeeeeeeeeeee'll float
G5   Bbmaj7     FTake life as it comes..."

play it as shown below:

Bbmaj7:  6x776x
