I have Random function...Songs not playing randomly?

So you're saying it's as simple as adding:

void setup() {
  // set up serial port
  Serial.begin(9600);
  randomSeed(analogRead(0));
  putstring_nl("WaveHC with 6 buttons");

and an antenna? I have two inches of copper wire now poking out of pin 0. Now it is playing a different song each time I start it up, which is hopeful, but not random yet. Am I doing something wrong? Please forgive me I'm totally new to this.

Cheers!
