I pay for Google Music (now Youtube Red) and tried out Amazon music and Tidal when I was trial'ing other music platforms. I didn't like their interface overall (subscribing, playlist, etc.) Despite the fact you can buy music outright from Amazon, I would rather pay a monthly subscription to Google Music/Youtube Red and get an unlimited amount of songs. Last time I paid for music was in the Microsoft Zune program before that got changed into Groove.
