Metallica is notorious for having issues with the internet when they were successful in ending Napster. Metallica recently invited music journalists and bloggers to a private listening party of their new album. There were no disclosure agreements signed or even spoken of. The event was reported on a number of different blogs and the new tracks were discussed.

Metallica got angry and sent notices to all the blogs to take down the posts regarding the band or legal action would be taken. Bad idea to piss off bloggers who have a loud voice on the internet.
