I understand your logic, but one would have to conduct an empirical
test to be sure. The problem is that having a different number of songs
on each album makes the empirical test somewhat more difficult to
conduct.  

I know how to compute a p-value, to be sure, but I just don't have the
time to do it right now.  Perhaps one of these days, when I don't have
something a million times more important on my plate, I'll try it. 
That should happen in about, oh, ten years or so.

Of course I raised the initial question, so I'm to blame.
