US music site Jango announced the launch of Jango Music Network (JMN), dubbing it as the world’s largest and most targeted cost-effective ad network for the music vertical.

The current JMN inventory of music sites reach a collective total of 30 million unique monthly visitors in the US alone. JMN also features a unique methodology that maps brand preference to musical taste and uses it to help advertisers target audiences that will be particularly receptive to their brand.

For example, ads run against the unique artist subset for Dodge Truck received a 273 percent higher click-through rate than ads run against the average artist. For Armani Exchange, the lift was 82 percent and for Gevalia Coffee it was 147 percent. Each brand had a completely different subset of artists, some expected, others somewhat unexpected. Dodge not only performed well with Keith Urban but also Justin Timberlake. Armani Exchange was not just favored by fans of Coldplay but also those of John Mayer; Gevalia Coffee shared a strong affinity with Bruce Springsteen but an even stronger one with Leona Lewis.
