Can rap lyrics amount to confessions to murder?
Song lyrics are usually understood to be fiction - Tom Jones's 'Delilah' isn't an admission that the Welsh singer actually stabbed an unfaithful girlfriend, and Bob Marley never "shot the sheriff".

But in California rap lyrics have been presented as evidence in criminal prosecutions in such a way that the state has now legislated to restrict the use of those lyrics in trials. And a murder conviction has been overturned, and a retrial ordered, for a rapper convicted on the grounds of his lyrics.
