+##SONG LYRICS SHUFFLER
+
+### INTRO TO ANGULARJS BASICS
+
+#### App
+
+You will make a static page that displays songs with the song title, author, year, and lyrics. For no really good reason other than to practise `ng-click` and execute controller functions, you will be able to shuffle the order of the lyrics by clicking a shuffle button, as well as hide/show the song by clicking on the title.
+
+Ultimately, you can add new songs to the page.
+
+Sample screenshot:
+
+![](screenshot.png)
+#### The app should:
+- Display song titles, authors, years, and lyrics line by line
+- Hide / show the song by clicking on the title (the title does not get hidden 'cos you still have to click on it to show the song again)
+- Shuffle the lyrics by pressing a shuffle button
+- Add a new song
+	- When entering lyrics, the user should separate the lines of lyrics with a comma. **HINT FOR LATER** when the form is submitted, the app could `split` the lines by comma for use in an array  
+
+#### Set up - you will need:
+- `index.html`
+- `app.js`
+- `style.css` if you want to add some style
+
+Server and database will be introduced tomorrow
+
+
+#### Angular stuff you will probably want:
+
+#####Display songs
+- A link to Angular 1.5 from https://angularjs.org/
+- module / `ng-app`
+- controller / `ng-controller`
+- `ng-repeat` ( you might want to include a `track by $index` in the directive params, but if you don't need to, then don't)
+- `ng-click` (hint: you can pass in $index as a param)
+- `ng-if` or alternatively, `ng-hide` and/or `ng-show`
+- curlies `{{ }}`
+
+#####Add a song
+- a form with an `ng-submit`
+- inputs that rout to `ng-model`s which could be inside a formdata object in the controller maybe.
+
+
+Overall, you will need data and functions in your controller.
+
+#####Sample data
+
+```
+this.songs = [ 
+  {
+	author: "De La Soul",
+    title: "Ring Ring Ring",
+	lyrics: [
+		      "Hey how ya doin'",
+	          "Sorry ya can't get through",
+			  "Why don't you leave your name",
+			  "And your number",
+			  "And I'll get back to you"
+			],
+	year: 1991,
+	hidden: false
+  }, {
+	author: "Ini Kamoze",
+	title: "Here Comes the Hotstepper",
+	lyrics: [
+			  "Here comes the hot stepper",
+			  "I'm the lyrical gangster",
+			  "Pick up the crew in-a de area",
+			  "Still love you like that"
+	        ],
+	year: 1995,
+	hidden: false
+   }, {
+		author: "Snow",
+		title: "Informer",
+		lyrics: [
+				  "Informer",
+				  "You no say daddy me Snow me-a gon' blame",
+				  "I lick he boom boom down",
+				  "'tective man they say, say daddy me Snow me stab someone down the lane",
+			      "I lick he boom boom down."
+			    ],
+				  year: 1993,
+				  hidden: false
+   }
+];
+```
+
+#####Shuffle function
+Pass in an array and the shuffle function will randomize the order of the elements
+
+```
+	  function shuffle(a) {
+	    var j, x, i;
+	    for (i = a.length; i; i -= 1) {
+	        j = Math.floor(Math.random() * i);
+	        x = a[i - 1];
+	        a[i - 1] = a[j];
+	        a[j] = x;
+	    }
+    	return a;
+	  }
+```
