Tidal does not post the cost to buy a song or an album on their site

I've used all (I think) streaming services and I (reluctantly) concluded that Tidal has the largest selection, highest fidelity and best search function. The price though seems very high to me.

Here's my question: When a Tidal subscription lapses and downloaded tracks/albums will no longer play, does that imply that there's some sort of DRM code embedded in the data? If so, does that digital watermark in any way degrade the fidelity? I haven't noticed, but perhaps I've not got the late HP's ears. Comments? Thoughts?

I would expect that like Spotify, Tidal offline mode has to be renewed by going online within a 30 day period or the files you have saved offline will no longer play. It’s either on or off so to speak, no in between.

Here's a link to the 'purchasing music' FAQ on Tidal's site:

It looks like you can indeed buy tracks or albums if you'd like, but that's not really what their service is geared towards, it's primarily a streaming service. 

The 'all sales final, one time download link' part isn't as friendly as iTunes where you can always re-download your purchases even if you somehow manage to delete them, and Apple does allow CD-quality lossless purchases as well.  

Don’t forget veterans pay $11.99 a month for the $19.99 top tier plan.  They will ask for a copy of your DD214 as proof.

One does not "buy" music, only the rights to listen to the music.  You may own the piece of plastic (or vinyl) that is the media for the music, but the rights to the music do not transfer to the owner of the media.

If you only rarely purchase music (a few times a year) and only listen to your music collection, and are satisfied with streaming low res content (for example, YouTube) and/or putting up with commercials (broadcast radio, certain streaming services, etc.), TIDAL will not likely be your thing.  If you buy more than an album a month, demand at least CD quality, and appreciate a certain amount of curation, organizational, and informational content, then TIDAL is a mind-blowingly good deal.  I subscribe to the family plan for $29/month, and I have 4 extremely grateful family members (along with myself) who enjoy TIDAL every day.  I have access to a gargantuan library of CD quality music, which can also be stored on portable devices, for about the cost of a Double Latte every month.  Decision does not require brain.
