The challenge asks for anime that I'm ashamed to have enjoyed. I'm not going to go with this since you shouldn't be ashamed to like what you like. It's kinda lame. Like what you like. That's how people work.
So instead, I'm doing my top five favorite openings or endings since music is really important to anime. It's also going to be in a different format. Monday will be an assorted group of some of my favorites while Tuesday-Friday will each have a different anime that had a bunch of themes that I liked.
Hope you enjoy!
