This semi-soundtrack to the Katie Holmes flick is an odd mishmash. Half the tunes are familiar fare taken from the best-known albums by Stephin Merritt's bands Magnetic Fields and the 6ths. There's also one unremarkable new Merritt tune written for the movie. Inexplicably, the disc also includes four brand-new Magnetic Fields tracks -- the first in four years -- that don't appear anywhere in the movie. It's these that will really interest fans, but while they have their charms, none can match the playfully sophisticated melodies and sad-sack wit of 1999's wonderful ''69 Love Songs.''
