This is free software available to download and install free for one day only.
In a nutshell it means you can play protected songs on any PC or player.
The software means that if you download songs and files from I-Tunes or other sites that have DRM (digital rights management) you can use this to wipe the DRM.
I-Tunes songs are generally restricted so they can only be played on ipods and other Apple products. This software gives you the freedom to choose. Yay!
