There are multiple methods on how I manage to grind music discovery in my own time.
1. Constantly go through Spotify algorithm for suggested artists (almost 1000 different artists are followed by me currently).
2. Find music that other people are interested in, like if they post it on some music sharing channel on Discord for example.
3. Pure luck sometimes haha (Like randomly finding the song on another platform, such as Soundcloud and Bandcamp)
Listening to albums (and having a varied taste in music) can really help with trying to find songs if you are less into going through algorithm suggestions, no joke. I keep mentioning about my song taste over the web but sometimes it's just hard to describe and I barely mapped any songs that I found solely from these tastes and such lol
