How can I preload my mp3 stream which is from a web link

I have my song playing from an mp3 website however I need to preload the song so that when I run player.play(), the song will start immediately with no buffering and also hopefully not buffer throughout the whole song. Is there a way to accomplish this or would the file have to be stored locally?

override func viewDidLoad() {
    super.viewDidLoad()
    appDelegate = UIApplication.sharedApplication().delegate as? AppDelegate
    println(test_)
    timer = NSTimer.scheduledTimerWithTimeInterval(0.02, target: self, selector: "saveTime", userInfo: nil, repeats: true)
    appDelegate.mpcHandler.sendSongInfo()

    NPMusicClient.sharedClient().urlForSongWithQuery("\(artistName_) \(title_)", success: { (url) -> Void in
        AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, error: nil)
        AVAudioSession.sharedInstance().setActive(true, error: nil)

        self.player = AVPlayer(URL: url)

        self.player.play()

        }) { (message) -> Void in
            println(message)
    }

    startplaying()
    // Do any additional setup after loading the view.
    println(boolValue)
    functionLevel()
