Tidal will let you search their catalog before signing up for a subscription. Check out as many streaming services as you can before making a decision. Each has their pros and cons as far as features and user interfaces. Catalog varies sometimes one has something another doesn't for no apparent reason and I'm not talking about exclusives either. Also sometimes one may have a deluxe edition and another may have the same album title but a different version. Stupid and unfortunate. You can always try contacting the service itself to request what is missing as well as trying to contact an artist direct to ask if they would try and make their missing catalog titles available to these streaming services.
