Ive downloaded over 150k tracks from tidal using tidal dl and after a lot of testing the most theyve done to counter is rate limiting or blocking the IP i was using, but if you stick with reasonable limits of how quickly you are downloading tidal doesnt seem to care much.
Typically the project will offer its own deb repos and packages along with setup instructions such as steam or docker
In theory you can add LMDE or other debian based distros repos to your sources but it will most likely lead to things breaking. If you cant find instructions specific to debian then you are better off either compiling from source or using snap, appimage or whatever pre-compiled option is offered officially.
I run an 8 disk 90tb BTRFS RAID0 and its been going strong for over a year. I hesitate to actually encourage anyone to live this dangerously but its mainly a media server and if i needed to i could restore any lost data from usenet or torrents using my arr stack which is on a different drive. If you can handle the risk its a nice speed boost.
