Worst use of music in a contemporary film, the nominees are:
David Thewlis playing fake Chopin in "Beseiged"
The unsubtle use of various pieces of "telegraph" music, e.g. Bill Withers, "Ain't No Sunshine" in "Notting Hill"
The dreary sameness of Star Wars' music (could John Williams please put a folklorist on his staff, so we could get some different local music for each world his people go to, rather than warmed over Erich Korngold/Gustav Holst throughout the Federation -- no wonder people want to rebel)

Anyone got a contemporary great moment? Most of the movies now seem to be have soundtracks just to have soundtracks. Something where music is used as an integral part of the movie, and not just as an ironic commentary.
Buena Vista Social Club is in a league of its own.
