MXP4, a provider of digital music marketing and distribution services, announced on Thursday that it has raised $4 million in a new round of financing, led by Orkos Capital.

Previous investors Sofinnova Partners and Ventech also participated in the round, proceeds from which will be used to roll out MXP4′s technology.

Paris-based MXP4 says more than 100 artists have used MXP4-powered Web and iPhone interactive music applications for viral distribution and purchases, including Britney Spears and David Guetta, along with brands such as Air France Music and Coca-Cola.

The applications offer interactive features that, for instance, let users create their own remixes of songs, or sing along to karaoke tracks.
