The attached file cannot be played by the latest
(0.15.0b) or previous (0.14.2b) versions of libmad (in
this case, using madplay). It simply reports lots of
errors:

error: frame 0: lost synchronization
error: frame 1: lost synchronization
error: frame 2: forbidden bit allocation value
error: frame 3: CRC check failed
error: frame 4: bad scalefactor index
error: frame 5: forbidden bit allocation value
error: frame 6: forbidden bit allocation value
error: frame 7: CRC check failed
error: frame 8: CRC check failed
error: frame 9: CRC check failed
error: frame 10: forbidden bit allocation value
error: frame 11: lost synchronization
error: frame 12: forbidden bit allocation value
error: frame 13: forbidden bit allocation value

Yet, mpg123 and xmms (on linux x86) and winamp (on
windows) plays this file fine.

    This is a problem in 0.14.2b that has been fixed in 0.15.0b.
    Some MPEG audio files use a reserved emphasis value in their
    frame headers; 0.14.2b rejects these (on the theory it is not a
    valid frame header) but 0.15.0b accepts them as long as the --
    enable-strict-iso option is not given to 'configure'.
