I always hated the Spotify UI. Now if someone could clone Rdio now that its on its way out. Then I'd be interested.
At the moment I have been using Tidal on a trial and I just keep finding so many small features I miss from Rdio. The only thing I like about Tidal is the Lossless option.
I'm in Canada so I didn't realize Deezer wasn't available in the USA.
As far as I know. Deezer is available almost everywhere except the US and Japan. I hope they figure it out soon. I"m glad to hear that you like it.
