A few days ago, an Internet Archive collection titled "90s Sample CDs" was DMCA'd. This collection contains many classic sample CDs from the 90s - 00s (Zero-G, Best Service, AKAI, Spectrasonics etc.) and the original archive.org page had over 14,000 views. With the help of a few other people, I have collected around 500 CDs from the original archive, and converted most of them from their original formats. Some of the disc images require proprietary tools to use properly, and will show up as broken or empty if you try to open them in an archiver or mount them as a disc. I have taken the liberty of converting what I can to uncompressed .wav files. Additional information from the original uploader can be found at https://pastebin.com/VaxsxX2a

The total file size is about 343GB, and I am seeding from a gigabit internet connection. At the time of writing I am the only seeder.
