I downloaded some music from Amazon, and when I've transferred it to my new Windows 10 laptop it doesn't let me play them until I've bought a Music Pass. Why?

I also recommend Exact Audio Copy if you want to rip your purchased CDs. I rip my CDs to FLAC format and play them using VLC Player. No additional plug-ins are needed to play FLAC and OGG formats using VLC Player.
VLC Player supports all platforms, desktop and mobile, too.
