In Brief: : *** “Pretty Woman,” EMI.

These days pop-rock sound tracks are usually unsatisfying packages featuring one or two likable songs and the rest filler. But this one, from the hit romantic comedy, is loaded with gems, from David Bowie’s updated “Fame 90” and Natalie Cole’s “Wild Women Do” to Red Hot Chili Pepper’s “Show Me Your Soul.” But there are two sappy clunkers--by Jane Wiedlin and Peter Cetera. The gem of this collection, of course, is Roy Orbison’s classic rendition of the title song.
