Is it possible to play musics using the Ess that are outside the data folder of the sketch?

I need the same songs in different sketches and I don't want it repeat many times.

I've tried this:

import java.io.File;
import krister.Ess.*;

void setup() {
 File dir = new File("Processing/musicas/01 Serenata Di Toseli.aif");
 println(dir.getAbsolutePath());
 Ess.start(this);
 AudioChannel mySound = new AudioChannel(dir.getAbsolutePath());

}

The file's path is right, at list the program prints the correct one, but it didn't work. It seens that the Audiochannel is trying to open some other file. Something like: sketchbook\sketch\data\dir.getAbsolutePath(), a path problem. When I run that code, I get:

C:\Documents and Settings\computador\Desktop\processing-0135\musicas\01 Serenata Di Toseli.aif

Unable to load sound: C:\Documents and Settings\computador\Desktop\processing-0135\musicas\01 Serenata Di Toseli.aif

Does anybody has an idea?
