OH! Sorry I completely misunderstood, I love that question.

Various ways. Sometimes I go to record shops, and go through the vinyls until I find something with a cool name or other arbitrary metric I've come up with to choose an album. This is how, many years ago, I found Foxboro Hot Tubs -i literally picked it up and thought, "well this sounds like it may be a funky band!" Then realised immediately that the lead singer sounded a lot like Green Day's Billie Joe Armstrong but singing entirely different styles. Turns out it was a side band of theirs!!

Other times I always keep Shazam handy when I'm outside, going for walks, meeting with people, going somewhere to eat, etc. in this way I've realised a lot of other people have very cool tastes so when I hear something I like, I literally pull out Shazam on my phone and see if it can figure it out.
For the moments it doesn't work, I usually find someone to ask. Doesn't always work though.

Other times I'm just going through each playlist on streaming services, like YouTube Music, and just skipping until I find something I like and then add it to a list.
I listen to various genres, however there are a lot of sub-genres alongside occasional fusions I would miss out on if I only go with the tunes I know, so I'm keen to just randomise the genres rather than focus on one solely. Cypress Hill is a good example, since there are a good number of tracks they did with a rock vibe, or that Korn track they did with Ice Cube. Many times I'm playing songs for the vibe I'm in at the time, so it literally can flip from Suidakra to Taylor Swift depending on my hectic mind haha.

Hope that answers your query.
