Because I travel 50% of the time, the ability to listen to my playlists/albums offline while on an airplane makes Spotify great for me. I used Tidal for about 3 days a few months back and thought the sh*tty interface wasn’t worth the increase in sound quality.
Tidal vs. Spotify
Tidal sounds better for sure. Search functions aren't as good as Spotify but if you are currently using Spotify, give Tidal a try and let me know what you think!
