A very odd idea

So I've been working on a little flash media player (only plays music) and I want to add an option where you can click the name of a song and it'd play it.

Doesn't seem too complex, corrent? Well I'm stuck.

What I have added:

Play, Pause, Reverse (goes back 1 song), and fast forward (goes forward 1 song)

Song data display (shows title and artist of each song)

Scrollbar (To scroll through the songs (Broken temporarly, idk why))

Array to place all the Movie clips (1 per song) in a box so you can click them.

and some other stuff.

The issue:

I can't pinpoint a good way to figure out what song is clicked for the player to know which song to switch to.

It loads via xml and plays using an int. The current_song int can only go as high as there are songs within the xml. If it goes further it resets to 0 and starts the list over.

So what I need it to do is set each song item within the array of movie clips to a number. When clicked the current_song int would change to that number, and then play the selected song.

I'm sorry if I'm confusing you. I'll try and explain better if you can't understand.
