The rating is not a reflection on the audio but on the way it is distributed. I simply haven't heard it.
I'm used to buying music from Bandcamp, etc. - I simply download it in whatever format I like and play it back on any device I choose.
Not with this though. I've wasted my money on this because I cannot install software on the device I want to use to listen to this audio.
Why was there no warning of this before I wasted my money?
