Are you sure who is spreading the bs? Perhaps a dose of IMHO is in order.
I did a search for a metallica album . Top result is a url 'www.amazon.com/exec/obidos/tg/detail/-/B00000000?v=glance' (Amazon browse page)
I checked backlinks and I found affiliate links with the url of 'http://www.amazon.com/exec/obidos/ASIN/B0000000/affid'
I don't think this was true a few months ago, though. Maybe Google engineers helped Amazon to redirect in a more Google friendly way.
