Gosh, the Amazon service sounds interesting.

Think I'll just take it steady and try a few of the trial players. To be fair, Spotify Premium is just so convenient and user friendly I will be keeping it for mobile use and kitchen system to bluetooth speakers (not to mention the kids phones) so Tidal interface on a PC is probably fine for my two main rigs. Just wish it could be controlled remotely by the app like you can with Spotify. Grant is right - Spotify with hi-res would probably kill everything. I wonder why they don't want to do it?
