SoundTaxi skips DRM protections and offers you a converted file for each input file you choose. You can choose the outpt format from a wide range of formats and qualities, so it's sure it will suit your needs.
SoundTaxi is very easy to use. You only have to add files you want to convert to the conversion list and the process will start automatically. It's really fast. However, you can adjust settings for each file if you don't want all of them to be converted to the same format nd in the same quality.
