Konoyo no Uta

This is the same insert song from the anime black cat. Sung by Iwasaki Taku. Soothing melody, great vocal. Here goes the lyrics(Taken directly from the subtitles of the clip):

Sekai no uta wo

Dokomade ikou

Sora wo aoide

Hito no fubu goe

Mushi no habataki

Fuwa fuwa fururin

Omoi nosete

In the anime, this song was sung by Saya Minatsuki on the roof. It was this song that caught Train Heartnet's attention. It caught mine, too! Cute appearance. Nice hair. Too bad, she died in episode 6. Way too early for such a good character to be dead.

Song of the World

This is an insert song from the anime Black Cat. English dubbed. Here goes the lyrics:

Sing a song unto the world

Rising high the clouds unfurl

Fan the planes into the past

Here now our lives will last

We'll never know the times of pain

Fall down fall down falls the rain

My life won't be plain
