Yeah, I think this is an unfortunate casualty of the AI age. Instead of discovering a weird fast food employee orientation CD or somebody's niche garage album from 1996 that was semi-accidentally uploaded by whoever happens to own it now, you're just getting thousands of fake songs made by bots.
I feel like it'd be worth it for someone to create an online library of CDs. People could send in their CDs if they weren't already archived, the music would be ripped and stored as flacs, and the CD would be sent back. The library could provide access to the files for the sort of thing nobody is going to issue a takedown for (aforementioned orientation CD or niche garage album) over the net
