Soundtaxi can remove DRM protection from Windows Media Player and iTunes. It works with every major music download and subscription service. It can even remove DRM protection from audiobooks from Audible. It has a high speed digital dubbing feature (up to 13x the playback speed). And it is slightly cheaper than MuvAudio.

Why should I use MuvAudio then? 'coz it have a nice affiliate program that can bring me some money?

What do you think? Is MuvAudio easier to use than Sountaxi or TuneBite? Is it more powerful? Does it really have any features that you need and other software lacks of?
