Software to convert MP4 to MP3

[Spacecadet]

Not a realistic option if we're talking loads of music here, but you could burn an audio CD from the MP4 tracks, then re-import the now-DRMless CD in whatever format you choose in your imported, MP3, etc.

Bit of a faff I'll admit though.

Burn to an ISO image then use a virtual CD drive to re-import

That was my one and only experience of iTunes. I bought an MP3 audio course that I wanted to play in the car, but the only possible way was to burn audio CDs from iTunes and then re-encode. But it needed 6 audio CDs, and iTunes, POS that it is, would only burn them all in one go and crashed frequently whilst in the middle. About 20 CDs later, and I finally had my set of 6 only then to discover iTunes hadn't respected the tracks at all. It did ultimately work, but never again.
