How do I select random music?

If I had 5 songs, how would a play them randomly, so if one finished, another random one would play, not the previous one though.

The simplest method I can think of is just to create a little counter using a global variable. Call is "Track" or whatever.

Now you create a function that when called plays the track according to the number of the counter variable.

Track = 1 -> Play X track

Track = 2 -> Play Y track

You have the "on finished playing" condition, when the music finishes it either randomises the Track variable again or adds 1 to it etc and then calls the function again to play.

Thx that helps
