I loved OiNK (and had the t-shirt), but neither What.cd nor waffles ever were a proper replacement for me.
What got me that feeling of discovery again, decades later, and even surpassed it, was doing release Fridays and just listening.
I mostly know what (sub)-genres I like, I go through upcoming release lists for the next week, open every bandcamp link in a new tab (or for those that don’t have bandcamp, I see if I care about the genre enough to search for a single on YouTube), and then I have maybe a hundred links, I sample everything for a few seconds and decide on yay or nay, and about 10 - 20 % go onto my excel sheet. Then on Fridays (up to Sunday, depending on how busy the release day is) I start listening to all those albums to see which of those I’ll buy (usually 1-2).
It’s some effort, but my appreciation for music was never this high.
I really loved OiNK and all of that era. Was genuinely gutted when it all fell apart, as it was also about the community of it all. Always wanted a tee - I'm envious.
When waffles and What.cd appeared it seemed to me like waffles would be the long-term successor, but definitely didn't work out that way. Neither ever felt the same, and I wasn't engaged with them like I had been on OiNK.
Nowadays I'm just another streaming service zombie when it comes to music, aside from my old library sitting in Plexamp, like my own little musical time capsule.
