Japanese music lyrics is not supported by Roon. I understand that this probably costs money and effort for licenses and stuff, so at least give us the ability to copy and paste our own lyrics into the lyric panel. (this has probably been suggested a lot of times).
Same with detecting Japanese albums and tagging them, not a single one will be found. This is kind of a nitpick because there are external apps like Musicbrainz who can detect and fix them.
Roon however does, identify this album by the same artist but displays the Latin album title and track names rather than the original Japanese which is not ideal.
I see similar things with other Japanese albums (Korean and Chinese as well) and normally have to set metadata preferences to prefer file tags over Roon data to display the correct tags.
