Heck yes. Music pirates have done a whole lot to help preserve hip-hop history by ripping/archiving countless rare/underground 12" and cassettes that are definitely not available on streaming platforms; we're talking alternative versions of songs like clean edits, remixes, acapellas, instrumentals which supported hip-hop producers and DJs in the early days.

For example, check the posts in the early 2010's of sites like this, https://hiphop-thegoldenera.blogspot.com/, of course all the links are broken now.

There is some rare stuff on YouTube - check out this channel - https://www.youtube.com/@OGDonNinja

Guy is a collector of old hip hop records and tapes from the 80s until early 2000s. They are all available on his channel in their dusty-sounding glory. Amazing.
