From Liquidgeneration: "According to law officers, Mathers was hysterical when police arrived and told them that she killed her boyfriend only after he accused her of illegally downloading music and erased about 2,000 of her MP3s. Mathers complained that it took 3 months to build her music collection."

Kids, this is why you should not download music from the internet. The best bit is that she was remorseful that she had spent so long building up her collection, and that it was gone in an instant. A further lesson that was learnt here is that you should back up often.
