Added warping, tremolo, bass boosts, pitch drops, slow-downs, a boatload of reverb, and one or two stutters. I did this, quite honestly, a slow weekend afternoon when I was bored. Enjoy it if you can, ignore it if you can't. This does not represent my true skill or effort levels. I don't own Dr. Horrible's Sing-Along Blog, any of the music, characters, or concepts.
