Deemix is still the best.

I unfortunately have to link to Reddit:

Main post: https://www.reddit.com/r/deemix/comments/zlswiz/last_update_is_now_out/

Archive of Main post (above): https://archive.org/details/deemix

Archive of download (as the main website cannot be verified/trusted as it was purposefully not renewed by the developers; someone can come along and snatch it for malicious usage, so beware): https://archive.org/download/deemix/gui

Please do hash-check with files (of the program/application) you download to ensure they have not been tampered with.

Then use an ARL (essentially a user API with premium account status):

You can download uncompressed .flac or compressed .aac or .mp3 files.

Enjoy.
