When I am playing MP3s, sometimes I see the orange Powered by Gracenote icon on the lower left hand corner in the Audio screen. I am aware what Gracenote is, but my HDD Premium nav does not ever display album art. The same MP3 on my phone, or PC, show album arts (purchased from Amazon.com). So what does Gracenote do for me except for occasionally taking credit for powering my music (which I am pretty sure is powered by electricity generated by gasoline).
