music loses portability as it cannot be transferred to many other popular devices (like iPods, etc.), can only be used on Windows Machines, and requires Windows Media Player 9.0 or higher to play.

SpiralFrog only gives you "ownership" over songs for 30 day lease periods. However you can easily retain ownership of your songs by renewing your membership each month and answering survey questions. With over 3 million songs, SpiralFrog currently has music licensing partnerhips with Universal and several independent labels. With its offering of free music downloads, SpiralFrog has joined other free music companies like Ruckus in this space.
