This is Interesting
Tidal seems to use the same Global Identifiers ( accessible by the share / by email copyable link)
e.g
Artist
Alison Krauss. = tidalhifi.com/artist/6602
Album
New Favorite by Alison Krauss. = tidalhifi.com/album/3044220
Track
New Favorite by Alison Krauss. = tidalhifi.com/track/3044233
and as seen before entities are different for a UK and a US account
as an example , playable on UK Account, not on US Account
Paper Airplane by Alison Krauss http://tidalhifi.com/album/6043300
I've a couple of days overlap for a UK registered account and a US one, so have a few days window for further exploration as time allows
and have accessed both via the Web interface and the (windows) Desktop App, from the US,
so will explore further, but its late now so will leave you with the following
UK Account desktop App
US Account desktop App
