... <p>Hatsune Miku is a Japanese computer program. The technology is called Vocaloid ("vocal android"). That means, songs sung by her are made with the computer. A seiyuu (synchron speaker) lent Miku her voice. As the user of the program ('Producer') you can make her sing everything you want - in Japanese. Other languages sound rather crappy, or at least like sung by someone with a Japanese accent - depends on the producer.</p>
<p>Miku is often used (and designed) for pop songs, but there are also a bunch of horror and/or suicide songs by her on YouTube. She's the most known Vocaloid (but NOT the first!).</p>
<p>Note: Since it's Japanese, Miku is the given name and Hatsune the family name.</p>
