Streaming Music and being able to keep them as your personel files

And I do believe you can "buy" a complete album on Tidal but not cheap and limited I think to MP3 quality so really a non starter.

Tidal, Deezer et al are really in the business of selling you a means to stream music on a monthly subscription not selling music per se.

A quick Google search gave me this
Not tried it as not something I want or need to do but may be of help

Agreed it would most likely constitute an infringement of copyright... In other words piracy.....not that it has ever stopped some folk.

Now THAT is interesting indeed!

Very simple once a member of tidal, Deezer, Spotify etc.
At least on tidal the proceedure is once you are highlighted on an album, there will be a drop down,menu on the right to access. This gives you options like, play, add to favourites and download.
If I remember right this option to download is only available to mobile devices and versions( android and iOS).
I know it does not exist on my desktop tidal app.
Good luck.
