I may have 2 eurocents to throw in.
You can kick the CD, so that's hardware.
The layout and depth of the physical tracks is standardized so strictly that if a CD-ROM reader/writer doesn't comply your recordings are completely worthless on other reader/writers. Firmware.
The filesystem is pretty much standardized - slight incompatabilities do occur, though. Though it can be faked on other media, the filesystem was designed for CDs. Firmware, but less firm.
The mp3 format can and does occur on any other type of filesystem, so pure software.
What of the mp3 is data? Not the algorithm to pull the signal
out of it - that's software.
The interpreted signal (a sequence of relative amplitudes) - however
distorted - is data, as are the compression ratio, the duration
of the tracks at normal speed playback and some information
about the recording.

When it is in a form suitable for CAM it is.
