A music downloading service that opened in Canada earlier this year is now hitting the road to offer its music in the U.S. The ad supported service, SpiralFrog, features more than 700,000 tracks mostly from Universal music and independent labels. There is a download manager which is not compatible with iTunes, and users are required to keep their membership current or they are cut off from the service. If a membership is not renewed within 30 days, download privileges are cut off and after 60 days the songs will no longer play. Membership is free and completely supported by ads. CBC Story here. To be honest, I haven't tried the service so I'll have to reserve judgment. The titles seem a little limited but then again so are Amie Street's and I'm liking that service.
