I was just listening to the Lost Highway soundtrack - I'd forgotten just how good it was, and how well the music suited the film. Particularly enjoyed Barry Adamson's stuff, as much as Badalamenti's, and of course, Bowie's "Deranged". Incidentally, that Rammstein track is probably the worst song ever to wake up to when you've fallen asleep with headphones on, in the dark.
Anyhow, it's up there with the best. What's your top five? I'd do a thread on scores, but I don't think there'd be many responses (though if people want to name 5 top scores in addition, go ahead), so let's keep this to soundtracks (ie more along the lines of actual songs/tunes, rather than orchestral motifs), though I'd rule out concert performances and the like (ie, Sign O' The Times, Gimme Shelter etc).
Mine (I haven't really decided on the order):
Dirty Harry - Lalo Schifrin
Lost Highway - Angelo Badalementi, David Bowie, assorted artists
Easy Rider - Steppenwolf, The Byrds, Hendrix, assorted artists
Superfly - Curtis Mayfield
Deep Cover - Dr Dre, Jewell, Michael Colombier, assorted artists
Special mentions to The Virgin Suicides, Withnail and I and Trainspotting
Would have had Tommy in the top 5 but couldn't decide if it qualified.
