Feature Request: MPEG4 Audio Ripping to MP3

[Illustrations]

Hello,
I request that you add MPEG4 audio ripping to MP3. I am interested in ripping the audio from MP4 files into the MP3 format. Since you already can rip audio from DVD's into MP3, can you add ripping of MP4 files?

Thanks.

Doesn't this work in File to Mobile? Generic audio mp3.
