But speaking of the greyed out issue... it seems pretty essential to have the grayed out songs just completely removed. Most people with little DLC just assume a person with a lot of DLC is taking forever to pick... when in fact they are just being forced to scroll through a setlist of hundreds of songs to find shared music. This would be a huge improvement for online play amongst avid DLCers.
