These rarities aren’t quite so rare, since they were part of last year’s Boom Box set. But more casual fans of Gwen Stefani and her alt-ska hitmakers can, without shelling out for multimedia extras, check out endearing, younger examples of the marriage-minded tomboy agonizing over the task of taming restless playboys. Songs like the stop-start rocker “Big Distraction” and the dubby, aptly titled “Leftovers” pale beside the singles. But the remix-ready mambo “New Friend,” self-help carnival ditty “Under Construction” and both the light-rock and heavy-cello versions of ballad “Everything In Time” are satisfying laments with truth-serum lyrics. And roughing it up a bit, Stefani attacks “Oi to the World” by jokey So-Cal punk godfathers the Vandals, with just-a-girl sass.
