SpiralFrog was entirely supported by advertising, allowing free download of its music. The ads were presented in the form of banner ads much like any news website rather than in the form of popups or adware. 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. Customers had to visit the site at least once every 60 days and renew their license by signing in or downloading a song, and the songs would work for sixty days after the last license renewal. In the event that the license should expire, it could always be renewed at a later date to restore function to the tracks. For songs that were on portable devices, the device had to be synced with a computer once every 60 days to keep the songs active. In addition to music, Spiralfrog had 5000+ music videos also available for free at 300Kbps streaming or 1000Kbps if you chose to download it. Spiralfrog boasted approximately 800,000 songs upon its launch and offered more than 3 million tracks for download. 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.
