I have been impressed with the Tidal/Alexa integration so far. I was expecting it to be slow to respond (vs. Prime Music) like using my Plex library via Alexa, but it is really seamless and fast. I guess I shouldn't be surprised since Tidal uses AWS. It made my decision to stick with Tidal a little longer. I did the Deezer trial, but Deezer had a few more playback hiccups vs. Tidal for me.
