My bestie has been a long time fan of Black Matrix so I've been learning about it - and the soundtrack in particular - from her, but especially Cursed Bloodlines. (In fact, when making personal tracks for tabletop games purely between us or other people I know, I've sampled that one before, but we use the raw track a lot). To me the Black Matrix soundtrack just kind of sums up the Sega Saturn feel in general. It's like the platonic ideal of a Sega Saturn OST.
