According to TorrentFreak, a confidential document is currently circulating among the music industry suggesting that Google might be looking at a lawsuit if they don't clean up their act as regards to protecting copyrighted material.

“Google continues to fail to prioritize legal music sites over illegal sites in search results, claiming that its algorithm for search results is based on the relevance of sites to consumers,” [the document states.]

"With a view to addressing this failure, IFPI obtained a highly confidential and preliminary legal opinion in July 2011 on the possibility of bringing a competition law complaint against Google for abuse of its dominant position, given the distortion of the market for legitimate online music that is likely to result from Google’s prioritizing of illegal sites.”

We're pretty sure nothing wil be done about this, but if the IFPI have their way it could mean Google will have to make some pretty hefty changes.
