I would like to write something about Ed Sheeran, just because he's a great artist and I love his songs :3
13+
</p>
14+
15+
<p>
16+
<span>I have been listening to his songs since his biggest hit, <b>Thinking Out Loud</b> came out in the fall of 2014 (Now, only behind his song Shape of You) and since then I was in love with his songs. And besides being a great artists, he is also an exceptional guitar player.</span>
17+
</p>
18+
19+
<div>I just <b>fell in love</b> with his guitar skills and how he innovates new beats and sounds only with his guitar to give a background effect to the songs he performs at live concerts. </div>
20+
21+
<p>
22+
He was the <strong>main reason</strong> I started to develop my interest in <em>playing guitar</em>. Here's his picture if you don't still somehow know who I am talking about.<br>
23+
<img src="https://upload.wikimedia.org/wikipedia/commons/c/c1/Ed_Sheeran-6886_%28cropped%29.jpg" alt="Why is it not displaying" width="200" height="200">

37+
</p>
38+
39+
<pre>
40+
But seriously, how in the world can you not know him.
41+
According to me, he is.....
42+
<b>The</b>
43+
<b>Best</b>
44+
<b>Singer</b>
45+
<b>Ever</b>
46+

47+
