Perhaps this is more what you are looking for: throw together a playlist with a particular "vibe". Doesn't have to be large, 5-10 tracks works fine. Either switch on enhanced and look at the suggestions, or use the separate section for suggested additions at the bottom. Add the ones that fit the vibe, reject the rest. Repeat. I've found that it mines niches particulary well and discovers new tracks much more effeectively than the pre-canned discover playlists, or daily suggestions.
