New online music service SpiralFrog says it's reached an agreement with the largest record label, Universal Music Group, to offer free downloads of its songs and is trying to reach similar deals with other record labels. U2, Jack Johnson, Gwen Stefani and Elvis Costello are among artists on the Universal label.
The service, to be launched in December, will be funded by advertising, rather than the pay-per-song model of the market leader, Apple's iTunes. SpiralFrog downloads will not be compatible with iPod players.
