No. I have the same thing in my car radio. This is usually not a
correlation thing, because you don't hear correlations, as soon as the
first track is different you are on a completely new trail and don't
tell me that you can hear a correlation like in
1 20 4 80 5 vs 2 40 8 160 10

What you describe usually is a bad randseed issue, that is: the same
start value is used on consecutive rand sequences instead of using
something like time() as a start value.
