"example,[hypothetical] you were intending to do a collection of recordings of American chain gang songs,and you are offered to review another collectors field recordings,of American chain gangsongs, acknowledge your objectivity is compromised and refuse to review."

'Course, you could always decide to do the review and not record the hypothetical album instead.

Or shelve it, put it off for a couple of years. 5 years? 10 years? Nah, better make it 20. Or would the knowledge that you were harbouring the intention of recording a collection of American chain gang reviews in 30 years time still be too much of an overbearing prejudice do you think?
