Zing Systems, a Mountain View, Calif. company that provides wireless download access for mp3 or digital players, has secured $12.5 million of a planned $13.41 million third-round of funding, according to a regulatory filing cited by PE Wire.

IDG Ventures Boston was joined by return backer Redpoint Ventures.

We covered the company’s launch here. Although Zing doesn’t solve the wireless download problem for iPod owners, it does it for other mp3 or digital players. Founded by former Apple exec Tim Bucher, the company allows digital media devices to connect to music services such as Yahoo Music or other online content sources.
