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.
