This piece (Frozen Fear) was a bit too synthy sounding for the listing description. Also, it wasn't INTENSE and HORRIFYING which were the first requirements.
The track called, Dark Chaos, was not scary enough. The sounds were too electronic. You might consider rereading the listing description and have a listen to the reference material.. Symphony No. 1" by Krzysztof Penderecki
The Owner of a TAXI Friendly Music Library needs INTENSE and HORRIFYING INSTRUMENTALS that would scare the living day lights out of you. A composition in te stylistic ballpark of "Symphony No. 1" by Krzysztof Penderecki is ideal. Quoting the source: "The tone of the piece will be somewhere between a psychological thriller and a horror piece. I'm looking for anything from simple drones to interesting musical abstractions (severe electric guitar distortion, or simple piano notes). Nothing should sound too synthy. I'm also NOT interested in any melodic tracks of music." Pizzicato strings, blaring horns, dissonant chords, etc., are all elements that will help you capture that terrifying vibe. Be sure you listen to the referenced piece of music to get a feel for the overall vibe. Take note that there are no melodic themes, rather, the piece is atonal and has no real structure.
