Just upgraded from Amazon Music to Amazon Unlimited yesterday, listened to a few songs in ultra-high def and wow! I have a free 30-day trial and will probably keep it.
Never had a need for streaming music, but a few months back Tidal had a free trial.
Couldn't stand it myself.
Terrible sound quality compared to my files, and 99.9 percent of it was crap I would never listen to in the first place.
Result...no thanks to streaming for me.
