just a quick question:

are there any bootleggs out there with songs from after 1997? I just can't think of any.
Seems like he's more careful with the recordings than he was back then.

The only way Prince is even remotely responsible for the bootlegging of his songs & that is that he records all his live gigs. These obviously fall into the wrong (or right) hands.

But artists arnt stupid enough to give their hard work away.
