Hikari isn't dead, they managed to save almost everything. This includes all anime OST, Otome CDs, Idolmaster, Final Fantasy and Ghibli related stuff. They are now working on saving Vocaloid/Utaite stuff, general japanese music (like idols/solo stuff etc) and game stuff. By the way all forum links still works but the forums will be closed for a while because all this shit happened because Lantis staff was there (but the owner said the forums will eventually be back). They have a backup (animemusicdownload.info
) but Hikari will eventually be back, don't worry about it.
For now you can use those sites here, they have most stuff you could find in Hikarihttps://utanimeost.com/https://hako.re/forum/https://asiauniversal.blogspot.com.br/http://asiamediablog.com/https://eimusics.com/http://jpopblog.com/https://www.tsdm.me/forum.phphttps://nipponsei.minglong.org/tracker/https://jpddl.com/https://shirodesu.net/http://otakuost.net/
tl;dr Hikari is currently saved and will be back soon, don't worry.
