every time I'd much rather listen to the Quboz version than my local version...very odd. I even had a high res version locally and a 44.1k version from Quboz...again, Quboz was 'better'.
I thought the value of Amazon Music HD would be new, modern high-resolution albums.
However, the largest blessing has been finding old albums that have been remastered with great SQ, including 24 bit/96kHz remasters.
For example, my teen years' favorite Metalllica Album "Kill 'Em All" (1983, their first album) is available in 24/96 and sounds unbelievable good!
