SpiralFrog was a very early music streaming service based in New York City that launched in the United States and Canada on September 17, 2007.

SpiralFrog offered free and legal music downloads, all supported by advertising, and was the largest site of its kind in North America.

Songs downloaded from the service could not be burned to a CD, put on more than two portable devices and would not work on Mac OS X or the Apple iPod, iPhone, or the Microsoft Zune.

However, they would work with any digital audio player or music phone that supports WMA PlaysForSure subscription services.

When active Spiralfrog.com had 3,000,000+ songs and 5,000+ music videos available for free download, and at peak had more than 6,000,000 monthly visitors, and 2.6 million registered users.
