alphadogg writes "A music industry group is warning some 50 website that post song lyrics that they need to be licensed or face the music, possibly in the form of a lawsuit. The National Music Publishers Association said Monday that it sent take-down notices to what it claims are 50 websites that post lyrics to songs and generate ad revenue but may not be licensed to do so. The allegedly infringing sites were identified based on a complicated algorithm developed by a researcher at the University of Georgia." The "complicated algorithm" (basis statistics using Excel and Google) is described in the NMPA's "Undesirable Lyric Website List." Anyone remember lyrics.ch?
