Madonna has described the leak of several new songs as "artistic rape" and "a form of terrorism". As music pirates trade what they describe as the singer's 13th studio album, Madonna claims the 13 unreleased songs are instead "unfinished demos stolen long ago".
If so, it was probably a long time ago. As time as progressed she has gotten rather old, and the risk of contracting disease is likely quite high at this point.
