This submission showed up on /r/listentothis a couple of weeks ago. I'm reposting it here because it is the finest and most on-point collection of music I have ever encountered. The original post from /u/theamazingsounds is included below.
Hello again fellow music enthusiasts!
1 year ago, I made a post about my ongoing project to create a collection with as many genres as possible, aiming to give listeners a convenient way to discover new music. It got many interested and since then more than 50 genres have been added, as well as descriptions for every genre.
I'm making this post to thank those following already, and am once again open for suggestions and ideas. I also made a subreddit called r/TheAmazingSounds where you can post about music that you want to share with others. It is currently empty but I will try to keep it active and reply often.
You can find everything on Spotify. It is synced with other services but doesn't convert all songs.
