Playing local sound file

Question

I need to play an mp3 file in my AIR app. But I won't
necessarily know the path to the file because I need to use things
like the storage directory. So, would I have to do something like
this to get that done:
var file:File =
File.applicationStorageDirectory.resolvePath("path/to/mp3");
var urlRequest:URLRequest = new URLRequest(file.nativePath);
and then load the sound from that? Or is there some way that
AIR has provided to skip the first step?
Thanks!

@ paus akid,
There are two things wrong here.
One, you should never use a nativePath in place of a URL.
This happens to work on Windows because the nativePath is
interpreted as an absolute path. However, on Mac and Linux, a
nativePath is indistinguishable from a relative URL. Since relative
URLs are resolved against the application directory (in general),
you get the app:/ URL scheme. So change:
var req:URLRequest = new URLRequest(file.nativePath);
to:
var req:URLRequest = new URLRequest(file.url);
The second issue is that you don't initialize your file
object before using it to resolve a second path. Instead of:
var file:File = new File();
file = file.resolvePath(currentRandomSong);
You should do something like this (using the appropriate
directory):
var file:File = File.usersDirectory("path/to/mp3");
