Location of a song in iPhone's file structure

[ignus graius]

Scenario:

1. There's a song my friend recorded in my iTunes library. I've synced this song to my iPhone, and I'd like to email this song to another friend.
   
2. I'm not near my computer, so I'd like to send it directly from my iPhone.
   
3. I have iFile, so I'm able to go into Media/iTunes_Control/Music and see the individual song files on my phone, but they're randomly renamed when they're transferred to my iPhone.
   
4. Is there a way to determine which file corresponds to which song, without individually going through and listening to each one?

Can't you just look for it based on date and time?
