NMPA Sues Motive Force
Motive Force LLC is behind LyricWiki. From an August 27, 2009 article in Ecommerce Journal: "The suit against LyricWiki [by the National Music Publishers Association] also states that the site "knowingly assist[s] and induce[s] third-party software developers to distribute copies of lyrics from Plaintiff's Songs to consumers' computers and personal media player." However, earlier this month [LyricWiki's] Sean Colombo published a letter on the LyricWiki API Developers Google Group telling developers that licensing agreements with big music publishers meant that the company could no longer add programmatic access to LyricWiki's collection."
Music publishers have waited way too long to do this and it'll be the whole RIAA thing all over again. The music publishing business may be bigger profit-wise than the recording business (and after all, before recorded music, publishing was "The Music Industry") so they've got time and resources to seriously entrench on this.
