It would be interesting to look at how user prejudices alter
perception of quality. For example, to see if Linux users (who know
the samples' format) vote WMA down.

That's why a blind testing utility is used:

For win32 users, yes. For users of other operating systems there is no
blind testing, that's why I specified Linux users, who are not tested
blindly but invited to comment on the quality of the files.

I'd be nice to look if, say, 50% of blindly tested users preferd wma,
whereas the for non-blind Linux users the positive attitude towards open
standards lowered the perception of wma quality.

Interesting study, btw. I'll be joining in.
