All the tracks they composed for the movie that I have heard are specifically meant for cyberpunk, I have a few (but not all of them) and I think I got them from iTunes. The album I bought is a compilation titled "Now I'm Just A Number: Soundtracks 1994-95". It lists seven songs although I would not class any of them as "songs" - there's no singing as such, plenty of ambient noise, some talking even but mostly it's cyberpunk inspired "musical sound" for want of a better description.
Do a net search for the album name and you should find a few vendors for digital download.
Also the soundtracks to the computer games Satellite Reign and Auto Assault are similarly ambient, moody tracks although Satellite Reign being a cyberpunk themed game (it's considered a spiritual successor to the Syndicate Wars game if you're familiar with that title) is obviously more cyberpunk styled. I believe some of the tracks are able to be listened to on paces like YouTube.
The soundtrack can be bought from Good Old Games here https://www.gog.com/game/satellite_reign_soundtrack but you'll need to make an account with them to buy anything. I think there might be a few other digital download vendors but I didn't search for them as I have the soundtrack from when I got the game

The Auto Assault soundtrack by Richard Dekkard (speaking of cyberpunk, that name, BladeRunner anyone...), was composed for an online, post-apocalyptic, sci-fi styled vehicle combat game. Personally I love every track and it's been on every music player and computer I've had, again, I got the soundtrack when I bought the game but the publishers killed it after only a year or two because it wasn't getting a subscription base like the fantasy MMOs at the time...

if you want to get it yourself you'll have to do a websearch and find someone whose distributing it for free.
It has 19 tracks composed by Dekkard and should run for just over 50 minutes, if you want the whole thing.
EDIT: To make it clear, the soundtrack was included in the Limited Edition version of the game.
Or if you're feeling like taking a chance, copies of the game are sometimes for sale on Amazon.com but may or may not have the soundtrack CD. The good news is that because the game is long dead, copies of the game are selling for about US$1 to $4 for a "new" game - the soundtrack is easily worth US$20-25 but because it was created specifically for the game and the game publishers didn't bother to make it available separately when they killed the game, it is not available for sale on CD or as digital download anywhere as far as I know.
And again, some of the tracks are available on YouTube to listen to.
AND MORE EDIT: Also, some good news, I have just found that the Microsoft store sells the soundtrack for US$10 here: -
