Ad-supported SpiralFrog announced that it is teaming up with another record label on Thursday, adding to the list of companies who will provide music for its online downloading service.

The American independent record label KOCH Records will begin offering the website access to its library of music for the December 2006 launch.

Offering young consumers in every country an easy-to-use alternative to pirated music sites will be compelling, said Bob Frank, President of KOCH Records. Our dynamic deal with SpiralFrog offers our artists the opportunity to connect with music fans around the world, and opens up new revenue streams.

SpiralFrog is one of several technology companies and music publishers forging alliances in an effort to suppress illegal music downloading, blamed by record labels for falling sales. The company said their service will be a high-quality alternative to file-sharing sites that are characterized by poor-quality music, missing song details, and spyware.
