Like most No Doubt bass parts, this one sits distinctly above average. Most other No Doubt basslines are a bit too predictable to earn five stars, but I say this pushes far enough to earn it.
The verses have a fun repeating scale in them, and the prechoruses have slow scales around the fretboard with the occasional triplet feel thrown in. What pushes it into five star territory is the bridge, which scales across the fretboard in a new manner (and contains the only HO/POs in the song), and the chorus, where one does a sort of anchoring deal, such as R Y R O R B, which is good fun.
It does have a caveat, however, in the outro. It's repetitions of the chorus, which starts to wear down, and although I love speed up songs, it makes the part become old all the quicker. When it switches, it's to a slow doublestrum on single frets. It's a pretty unsatisfying finish to overall universally enjoyable song. But it's short enough to where it shouldn't detract from the rest of the song, so I say pick it up.
