I want to make one sound play right after another one ended, without any lag, like it was one sound file. Any ideas?

I needed the same thing, a playlist. I wrote the following script. I hope this will be helpful for someone!

public var controlledAudioSource: AudioSource;	// The audio source that will play the audio clips
public var audioClips: AudioClip[]; 			// Array for the audio clips
public var loop: boolean = true;				// Indicates whether the play list should loop when finished (start from beginning)

function Start(): void {

function PlayCurrentClip(): void {

}

/*

function PlayFromIndex( index: int ) {

	if (iterator + 1 <= audioClips.Length) {

		// Set the new start iterator:
		iterator = index;
		
		// Play the audio clip:
		PlayCurrentClip();

	} else {
	
		// This is not allowed:
		Debug.Log("Index " + index + " is out of the audio clip range.");

You can create your own AudioClip
http://unity3d.com/support/documentation/ScriptReference/AudioClip.Create.html
And read data from other in the correct sequence
