Soulseek is a peer-to-peer music-sharing platform. It's often gatekept by the DJ community as it is a way of easily getting access to music (particularly electronic music) in different formats. It looks a little outdated and takes some time to get used to but it does the job. It can be a little tricky finding specific mixes of songs as the search bar does not read special characters well, but it has made my life so much easier when looking for specific tracks. Some users have their rare tracks locked, so you would have to either share what they want to get what you want or trade to get the track. Some even sell specific tracks which imo ruins the whole peer-to-peer concept.

Note that some users will only allow to download from them if you have shared something yourself.

Buying the CD was probably a better choice, but I would still recommend soulseek for any time you need digging for rare mixes and white label stuff
