I suppose figuring out the correct length of a VBR MP3 would involve
reading the bitrate of every single frame in it up-front. (Mind, a
running average wouldn't be that hard, surely? Alternatively, LAME
could go back and re-encode the first frame of a VBR MP3 in the most
representative bitrate possible, so that at least those players which
derive their length estimate from the first frame and never update it
can get a little closer.)
