I'd recommend anime music videos for 2013.
"Anime music video" is a combination of music and anime. It may be created by the producers of anime or music, or created by fans who like anime or music or like both. In 2013, lot of great anime were aired in Japan, whether it's Shingeki no Kyojin (進撃の巨人), Kill la Kill, Non Non Biyori (のんのんびより), and they are known throughout the world. So it is a good thing to make anime music videos for anime fans can watch them later.
I would recommend "AMV" / "Anime Music Video" which were pretty interesting as follows...
Sword Art Online is an anime series about online games in the future where people can connect the mind and body into the game.
Fairy Tail is an anime series about magic and dragons. Every person has a different magic, but each of them meet and adventure together.
One Piece is an anime series about pirates and sea adventures. This is the most popular anime in Japan. Adults and children are well known.
Shingeki no Kyojin is an anime series about mystery between humans and titan. Titan is the most formidable enemy. They have many secrets such as why it exists and where it came from?
And of course, there are plenty AMV on youtube. You can get them all the time.
