Hell hath no fury than a Napster fan spurned, it seems. Hot on the heels of Metallica's major legal action against the developer of the MP3 track finder, the band's Web site was hacked over the weekend. A Napster buff sneaked onto the the rockers' server and replaced the site's minimalist www.metallica.com homepage with the equally minimalist 'LEAVE NAPSTER ALONE'. The site was soon back to normal, but the hack's effects can be viewed over at Attrition.org's site. But will the purveyors of some of music's more aggressive tunes hear the hacker's plaintive song? We suspect not. ® Related Story Metallica sues Napster
