Normally, I burn iTunes music to a CD to remove DRM so that I can listen to my music on every device. This method cost a lot of money and time. I am considering of buying CD instead until I get to know this product. It adopts virtual burning technology so the burning process do not need a CD-the converted songs are in the preset folder of your hard disk. This is the most amazing feature for me. This software supports a variety formats including m4p to mp3,m4p to wma etc. I no longer care about the compatibility problem because NoteBurner can convert all kinds of formats to mp3. Just the software what I am looking for.
