With the new launch of MySpace Music, they've also launched a new way to target the musicians surfing the site. According to this article at Social Times, this new self-service ad targeting service allows advertisers to choose which users see which ads selected by demographics.

After creating an ad that is either 728x90 or 300x250, the advertiser can choose to have it's ad targeted by gender, age, location, specific interest or categories (such as music, movies, fitness and health, etc) . Then, users are broken down target audiences according to the selection of the advertiser. These campaigns run on a cost per click basis rather than impression.
