I think you're right, it's a European thing, and it probably shouldn't have been printed on a CD sold in the US. One recent Metallica CD actually says "For sale or rental for private home use only." Of the US-purchased CDs I checked, major label and indie, none of them prohibited renting or lending. Of the 3 CDs I checked that I purchased in Europe, 2 prohibited renting or lending. One from the Netherlands says "Unauthorized copying, hiring, lending, public performances of the record prohibited." One from the UK (from 1994, so it isn't recent) says "unauthorized copying, hiring, renting, public performances & broadcasting of this recording prohibited." I think they use "lending" and "hiring" because "renting" in ambiguous as to who is paying or being paid.
