I'm going to quote Steve Watson, he is much more alarmist than I could ever be about this one. :)
------------------------------------------------------ After cracking down on MP3 file sharing, the music industry is to go to war against websites offering unlicensed song tabs and lyrics. The Music Publishers' Association (MPA), which represents US sheet music companies, says all such sites are illegal and will begin the crackdown in 2006. MPA president Lauren Keiser said that not only should sites carrying song tabs and lyrics be shut down but also suggested authorities should "throw in some jail time, I think we'll be a little more effective". Such tabs and lyrics are widely available all over the internet and are often simply the efforts of fans to interpret and play their favourite and much beloved songs. The legal blurb on this website actually says The tablatures contained within this site are artists' representations of songs the 'tabber' has heard. We are being led to believe that sharing information is illegal. Share song lyrics? Go to jail |
