Sour Musical Notes on YouTube, MySpace

A spat between Universal Music Group and Web sites that feature music videos is getting uglier. Universal is up in arms over what it says is the illegal appearance of its artists' videos on various sites. The music publisher has made its dismay known in discussions with online video giant YouTube.com and social network MySpace, a property of News Corp. (NWS). But while MySpace may be willing to play along, talks with YouTube have stalled, according to a person familiar with the matter. Universal is weighing a copyright infringement lawsuit against YouTube before the end of September, the person tells BusinessWeek.com.
