Some soundtracks stand on their own; this doesn’t. Lyle Lovett’s score for friend Robert Altman’s new movie Dr. T and the Women is all too self-effacing — not one new song features Lyle’s vocals. Instead, we get 13 pieces of background music by the Large Band, two recycled Lovett chestnuts (”You’ve Been So Good Up to Now” and ”She’s Already Made Up Her Mind”), and a nice, gospelish remake of another (”Ain’t It Somethin”’). For soundtrack collectors and Lyleoholics only. C
