The Wall Street Journal (subs. req.) reported today that music giant EMI is putting out a few feelers to gauge interest in selling their music collection–get this–without copy protection. This report comes in the wake of an open letter by Steve Jobs earlier this week about abandoning DRM altogether, and a subsequent denouncement yesterday by Warner Music chief Edgar Bronfman Jr. during an address to investors.

Wow! What a sequence of events! The lines are quickly being drawn, EMI on one side, Warner on the other, Jobs presumably on the EMI side (although is this a case of an industry player calling his bluff?). Where do the other players sit–Microsoft, Amazon, Sony BMG, Universal? This is shaping up to be a battle royale and we have a front row seat.
