CDM music is one of the few labels whose demo files are 320k MP3s
When you play back the files, they will downloaded in your PCs cache. If you are not as tech savy to grab them from there, I just prepared a little workaround:
The direct link to the demo files on their server and of that album is:
cdm-music.com/music_cdm/CDM048/CDM048_XX.mp3
Replace "XX" with the track title (e.g. 01, 02,...), such as:
cdm-music.com/music_cdm/CDM048/CDM048_02.mp3
for Track 02 ("Perfecto").
Please take care of possible underscores because I don't know about their internal naming scheme.
If you do that and access that link, it will open a bland player in your browser. Right-click into that player and it will offer you something like "Save to disk" or similar. Some browsers might download the file directly to your default download folder on your computer instead of attempting to play back. Also, accessing the site is rather slow today, so give it some time.
Just rinse and repeat down to track 25 and you have the disk directly from their site. I checked the spectrum: The files contain up to 20kHz and are true 320MP3s
EDIT: You said you want earlier stuff - and some of them is really good! - the same scheme works seemingly for all CDs.
Pick the CD number - some are discontinued, sometimes tracks are discontinued too (some CDs contain only 2 tracks; NICHION had these in the past but it's gone), referring to discogs:
https://www.discogs.com/label/732935-CDM-Music-Library?sort=year&sort_order=ascFor example
INDUSTRIAL ADVENTURE is disk 06, so if you want that, you just access the album, but now it's "CDM006" obviously.
cdm-music.com/music_cdm/CDM006/CDM006_XX.mp3
It takes some time this way instead of getting fully prepared disks, but I had a good weekend browsing and adding track by track to my drive and discovering the music. Maybe some people have the disks, but if not, you have the solution of "DIY"
Also, maybe there is a script or a batch downloading process so you can feed whole lists of links to download, such as:
cdm-music.com/music_cdm/CDM048/CDM048_01.mp3
cdm-music.com/music_cdm/CDM048/CDM048_02.mp3
cdm-music.com/music_cdm/CDM048/CDM048_03.mp3
et cetera and let that script do its work. I think I have seen batch download command like this. That would speed up your process of getting whole disks by a lot.
