This is a blog. A music blog, even.

So it makes complete sense that I post about “Dr. Horrible’s Sing-Along Blog” here.

Haven’t seen it yet? Well, here are some good reasons why you should:

* Joss Whedon wrote it

* Nathan Fillion plays a stupid superhero who refers to his penis as a hammer

* Neil Patrick Harris has a really nice vibrato. When singing, that is…

* Felicia Day is about the cutest thing ever

* It’s funny

All three acts are up now. Go watch! (ETA: All parts will be taken down midnight (EST) on July 20th, after that the show will be available to purchase via iTunes)
