James Horner's entry is perhaps most surprising because of its originality, based entirely on a witty pizzicato string backdrop, with other instruments added to ratchet up the tension. Several of the episodes have surprisingly cheerful moments and Loved to Death is almost entirely upbeat, with a sax line that could probably work as porn music. Of the other famous entries, Bruce Broughton's is actually a bit uninteresting and is rather anonymous synthetic creeping around music, only becoming interesting at the close, while David Newman's sounds like a synth demo from one of his Bill & Ted scores and Ry Cooder's is, perhaps unsurprisingly, led by twanging guitar for one of the most laid back excerpts.
Most, if not all, of the music is synthesised, but more often than not is simply a stand in for acoustic instruments. However, given the generally sparse orchestrations, this doesn't present a great problem. Featuring only a few minutes from each score is both an asset and a hindrance, the former because most TV music isn't worth presenting in much more than a brief sample, but the latter (especially in this case) because there is no overall mood or musical evolution. You might expect a gothic creepiness throughout, but clearly some of the music was cheerful - maybe for ironic effect? Maybe it's wrong to view it as a soundtrack album as it's essentially a compilation of highlights, but most of the highlights are worth hearing and fans of the show will love it.
