There were plenty of porn archives at the time, you'd just have to download from dodgy Finnish ftp sites or irc bots or binary newsgroups on Usenet. What wasn't available was the mass ripping of entire albums, although again, there were fairly substantial libraries on irc channels on EFnet and Undernet.
By 1997 there were also huge web archives like mp3.com that more or less just openly pirated audio, inspiring things like Napster. I believe Napster was specifically inspired by irc bots, particularly to get everything in one place (big mistake) because otherwise piracy involved a lot of laborious sifting through irc channels with virtually no security.
Most of these involved a direct client-to-client (DCC) protocol connection which involved letting some sketchy bot have your IP address and directly serve the file. This used to be a good way of getting a bunch of bots together for a DDoS especially with clients with widespread known vulnerabilities like mirc.
Anyway, you could do this stuff if you knew what you were doing but in the early '90s mp3s weren't really a thing (even though mp3 dates all the way back to 1991) and straight up full rips of CDs were completely impractical.
And even if you were someone who could deal with mp3s the likelihood of rips actually being out for whatever you wanted was low other than the most popular things of the day and weird stuff like Grateful Dead bootlegs, which were absurdly popular on early Usenet for some reason (John Perry Barlow of the founding of the EFF was actually a lyricist for the Dead as an example).
