Yes tidal is a definite step up in sound quality and from April they're making their hi res content available as part of the normal pricing tier rather than a more expensive tier.
I tried qobuz but the step up in quality didn't justify the added cost imo.
Spotify are also the worst at payouts to artists I believe.
Os Mutantes are excellent and really push the psychedelic angle.
Also the sole album by Arthur Verocai is brilliant. Some really creative arrangements.
