I think what he has is the following MP3 stream:

end of frame X
full frame X+1
start of frame X+2
<icy data>
end of frame X+2
frame X+3
<icy data>
[etc.]

Which is indeed not detected as MP3. It isn't. It's icy. Cut out the
icy in the icy demuxer, probe with that and you've got...mp3!

(I might be wrong, but I coded an icy demuxer before and this is what
I remember from it.)
