Now I am not referring to any hiss or picking up background electronic
noise at 100 % volume with good headphones. That's there all right, but
it's not what caught my attention. What I found was that some songs seem
to have random ticks and blips, and they are ALWAYS at the EXACT time
index in the song. I can even shut the thing off, and the same blips are
still in the same place.
