Thanks again, Stefano.

Your code pretty much matches what I posted originally, but my test was 
failing. I think I've isolated my problem....

I oversimplified things in my example. My actual program has several 
moving parts -- Song, UserConfig, Jukebox and system calls -- and I 
think that's causing my problem. Here's what's supposed to happen:

1) Jukebox is supposed to create a @current_song (which it does)

2) @current_song is asked to play itself (based on @user_config)

3) @current_song then starts a system process (via fork...exec or 
Spoon.spawnp) to play the actual mp3/ogg file (which it does)

4) Jukebox is supposed to remember what song it's playing, but when I 
ask Jukebox to tell me the @current_song, it says it's nil.

It's as if Jukebox forgets @current_song as soon as it tells 
@current_song to play

I didn't have this problem before I refactored Song out of Jukebox, so 
I've done something stupid.

I'll figure this out tomorrow.
