hello:  
i’m trying to create an mp3 player…  
buttons are created dynamically by loading xml file.

i can only get the duration of the mp3 after i “loaded” it.  
how can i display the duration of each song without  
loading it? i want it to display like (pls see below), after xml file is loaded:

song\_1 - 03:51  
song\_2 - 02:53  
song\_3 - 04:25  
etc …  
etc …

\*i already have the timeformat to display “00:00”

any input is very much appreciated.  
thanks in advance.
