idk about you, but i almost always have some of artist thats teetering on the edge of my hypothetical taste. Usually a song or two. If you have any just go listen to their collective works. Otherwise, try and explore genres you like, specifically ones with lots of variety, electronic music in particular is highly variable. Which is one of the reasons i really like it.

One thing i find that helps bring more music to the forefront is weird/abstract media. A lot of times people working on visual art, will back something with music they enjoy, especially if it's something more niche, the music is very likely to be a reflection of their personal taste, which is always a good strat. Sometimes that's movie soundtracks, other times it's just weird shit like an ARG that throws boards of canada in there for no reason.
