This song has been in my head all day. I’m sharing it with you! The song is by Jonathan Coulton. http://www.jonathancoulton.com/. He makes MMO related music and videos. The few I’ve watched revolve around WoW. The tunes are fun, but I believe his videos are patronizingly simple. An example is if the song mentions death it shows a dead body. If the song mentions a heart, it will show a picture of a heart. Although that is pretty accurate, it is also simplistic lacks the artistry that the fan made video below contains. It is pretty funny, catchy and it reminds me of my boyfriend XD
This particular video is fan made, and was been entered successfully in AMV contests at anime conferences. The anime that the video take from is called Legend of Black Heaven. I hope the music gets stuck in your head too.
