I'm not a believer in illegal downloads, but I think that going after guitar-tab sites is a little ridiculous. The New York Times has the story:
"In the last few months, trade groups representing music publishers have used the threat of copyright lawsuits to shut down guitar tablature sites, where users exchange tips on how to play songs like 'Knockin’ on Heaven’s Door,' 'Highway to Hell' and thousands of others.
"The battle shares many similarities with the war between Napster and the music recording industry, but this time it involves free sites like Olga.net, GuitarTabs.com and MyGuitarTabs.com and even discussion boards on the Google Groups service like alt.guitar.tab and rec.music.makers.guitar.tablature, where amateur musicians trade 'tabs' — music notation especially for guitar — for songs they have figured out or have copied from music books.
"Assuming a tablature site musters the legal resources to challenge the publishers in court, some legal scholars say they believe publishers may have difficulty arguing their complaints successfully. Jonathan Zittrain, the professor of Internet governance and regulation at Oxford University, said 'it isn’t at all clear' that the publishers’ claim would succeed because no court doctrine has been written on guitar tablature."
I shouldn't get involved, because I have a personal stake in this. After all, without tab websites, I could have never figured out that the chorus of"Waterloo Sunset" is G/D/E.
