OK, I take that back as well!

I found this command, and zsh interface, works, and it
isn't any less slow with m4a:s turned into mp3:s.

    img-song () {
        local img=$1
        local song=$2
        local new=$3
        ffmpeg -loop 1 -i $img -i $song \
               -c:v libx264 -tune stillimage \
               -c:a aac -strict experimental -b:a 192k \
               -pix_fmt yuv420p -shortest $new

The result file is:

    ISO Media, MP4 Base Media v1 [IS0 14496-12:2003]

Feel free to suggest improvements to the command tho :)

The mp4 is 8.3M, the m4a 6.7M and the png 2.7M.
