I have been on youtube premium for years. Can't image watching videos with constant ads. But I'm not a fan of YT Music, because of the interface, also don't like mix of videos and songs. Was long subscriber fo Spotify, but now I'm evaluating #Tidal.

Interesting! I do watch a lot of YouTube videos so there is a use-case for signing up to include YT music. But as you say… the interface! I trialed Tidal and I liked it and it includes many music videos too. However, it left a load of orphaned files on my devices, which put me off a little.
