Take a look at Musicroamer
you type in a favorite artist and it uses the spotify recommendation stuff to find similar artists
if you find one that sounds nice then you can then create a branch of artist that are similar to them
(probably a horrible explanation, just mess about with it for a minute and you'll get an idea how it works)

I've personally used it to find quite a few new favorites since ditching Spotify in favor of a self hosted Navidrome server

as for FLAC downloads check out Qobuz, which has unlimited DL plans
alternatively if you would rather sail the seas, search up Firehawk52 for a guide

I'm currently in the middle of a few books, and I've got more queued up to read next.
here's what I'm currently reading:

William Gibson - Neruomancer [The Sprawl, book 1]
Just started the last chapter, can't wait to read the rest of the sprawl.
the writing is amazing and i can see why it's so recommended.

Douglas Adams - The Ultimate Hitchhikers Guide to the Galaxy [Compilation of the entire series in one book]
I'm about half way through book 1, loved the movie and figured i would read the books.
no regrets so far, quite a fun read.

Martha Wells - Rogue Protocol [The Murderbot Diaries, Book 3]
Saw this series recommended years ago on reddit, only semi-recently got around to reading it
it's an interesting story, and i would recommend it myself.

Oscar Wilde - The Picture of Dorian Gray
I don't really even know what to say about this one, other than I'm enjoying it thus far
and the fact that i can't read more than a few pages at a time without getting a headache from deciphering some of the wording haha

and here's what's all on my to-be-read list (minus continuations of the aforementioned series) in no particular order:
Liu Cixin - Remembrance of Earth's Past [Series]
Neal Stephenson - Cryptonomicon [Series]
Neal Stephenson - Snow Crash
Frank Herbert - Dune [Series]
Harper Lee - To Kill A Mockingbird
Philip K. Dick - Do Androids Dream of Electric Sheep
Homer - The Iliad
Dante - The Divine Comedy

I would love some recommendations from you lovely people to add to my backlog :)

https://www.qobuz.com

you can purchase individual albums through the download store.
or you can buy a month of the unlimited download subscription and download everything you want
can be downloaded in either MP3 or lossless FLAC (though, don't download above CD quality because you won't hear the difference)

there also may or may not be a set of resources out there under the name Firehawk52
