The problem with mp3 is, that it can use different compression algorithms, 
which may compress the data dynamically i.e. depends on the pattern found in 
the sound. So it is difficult to calculate the length directly from the given 
file and that is the reason, why the length may be written in the ID3-Tag.

So the tip Dimitris give, seem to be the best solution.
