For those who don't know, MusicBrainz is a online database of music and such, and as fans, I think we should all take part in making sure that such a database contains all ayu's work, as well as making sure the database is correct.
If you go and sign up, you'll be able to make changes to the entries that are wrong and what not, so I urge you all to take a look! :D
