Well, what do you know, you are right, the version of foobar2000 I had was foobared.
It still has that same problem with the SOM "Secret of Mana Beyond Comprehension" song, but seeing as Winamp and iTunes gets it right, the foobar2000 program still needs some work.
Come to think of it, I did recall reading about some problems with ID3 tags(i.e. how to read other player's malformed junk, some popular ID3 tags not being official ID3 standard ones, etc), and why the FB2k team didn't like them..... So that would sort of explain things.
