I just noticed that apparently Magnatune samples don’t appear properly on pages showing lists of songs, although they appear properly on the individual song pages.

So, for example, look at the individual page for septahelix’s “outside looking out”:

http://ccmixter.org/files/s...

There are 6 samples listed on that page, but on septahelix’s upload list page, only 3 show up (the 3 non-Magnatune samples):
