Melissa,

This article was mentioned by Jon Longoria at theReformed (source: http://www.thereformed.org/2008/04/24/apple-wins-by-the-numbers/ ) regarding MySpace's challenger music service to Apple's iTunes which was a follow-up to his original article (source: http://www.thereformed.org/2008/04/07/myspace-gambles-big-on-lost-cause/ ). Although both are interesting reads, I would have to admit that Jon Longoria makes a better case on the probable outcome of MySpace vs iTunes.
