Don’t you have access to “Discover Weekly” anymore? My MO is: start curating some playlist based off a genre or theme, start radio from it, keep adding suggestions that fit and I like. Then have a huge playlist with my “I really liked and would play this anytime” and if I find I’m replaying a new song it goes there as well, then, based on your new searching and adding stuff, your next week’s discover might get a lot more interesting. Also shazam stuff on the go and add it to respective playlists, even maybe IFTTT to a Shazam playlist, and even (we need to find a fediverse alternative but I had IFTTT setup to add to a Reddit playlist picking from Music and ListenToThid top posts as well) . So, basically, you need to branch out first so spotify can continue to branch out for you.
I’m a software dev, early adopter of most techs I find, and I had like more than a week trying stuff out to replace he-who-shall-not-be-nameddit. After some trial and error, and wefwef, I’m confident I found a replacement. But I seriously doubt most people will adopt it. I think the communities will diverge, and I will think of Lemmy as the new reddit and reddit as the new Instagram anyway.
