Are There Official Soundtracks For The Billionaire'S Dark Desires?

If you're hunting for music from 'The Billionaire's Dark Desires', here's the lowdown from someone who loves chasing down forgotten soundtracks and limited-edition singles. After poking around official stores, streaming platforms, and fan communities, the situation is a little mixed: there isn’t a widely marketed, standalone full 'Original Soundtrack' album released under that exact title for the source material itself (especially if you're talking about the original web novel or manga). However, that doesn't mean there’s no official music tied to the franchise — depending on which adaptation you're following (drama, audio CD, or a televised adaptation), there are usually officially released pieces like theme singles, character songs, or drama CD tracks that serve as the closest thing to an OST.

For adaptations like a live-action drama or an animated series, production companies typically drop opening/ending singles and a few character or theme tracks. Those often appear as CD singles, digital singles on Spotify/Apple Music, and sometimes bundled as bonus discs in special edition Blu-rays or limited manga volumes. If you see a composer credited on the adaptation’s page, search their name — sometimes composers release their own compilations that include the show's background music even if the franchise never issued a branded soundtrack. There are also drama CDs released by publishers in some regions, and those sometimes get their own music tracks; check the publisher’s official shop, CDJapan, YesAsia, or the production committee’s store for imports.

If there truly isn’t a dedicated OST, fans often fill that gap fast. You’ll find fan-made playlists on Spotify and YouTube that collect the official singles, character songs, and similar-sounding instrumental pieces. There are also piano covers, violin arrangements, and remixes uploaded by fans who adore the series’ atmosphere — these can be great if you’re after the emotional tone rather than the exact official BGM. A practical trick I use: look up the performer of the opening/ending themes or the composer and then search streaming platforms for their discography; often the exact tracks exist under the artist’s name even if the series never got a packaged OST.

Where to look first: official publisher or studio websites, Bandcamp for indie releases, mainstream services (Spotify, Apple Music, Amazon Music), YouTube for teasers or full tracks posted by rights holders, and secondhand marketplaces for physical limited editions. Be mindful of regional releases and timing — some tracks show up in Japan/Korea first and get global streaming later. Personally, I love the scavenger-hunt aspect of finding those little singles or drama CD gems; they make the listening experience feel like a secret shared between fans. Happy listening — digging through those credits and playlists is half the fun and I've scored some absolute favorites that way.
