kyary pamyu pamyu - Yumeno Hajima Ring Ring

I don’t really like all her stuff, but she’s got some decent songs, like this one.

EGOIST - The Everlasting Guilty Crown

EGOIST – The Everlasting Guilty Crown.

Not sure if this song was from an anime or not, but it has a nice sound.

If anyone knows, please let me know.

Not sure who the artist is, but the song is called Humpty Dumpty
