I also mentioned the mp3 quality in the older post, nobody still gave a response to it. I said I can give you a better one without changing offset. Yes, it is a suggestion, but you need to respond to everything with a reason. For the time being, I'll leave the sample-exact mp3 here. You are not forced to use it, but at minimum give your response to it.no i don't want your mp3, better now?
SILENT SIREN / Silent Siren / サイレント サイレン / サイレントサイレン
Regarding the artist field. When Silent Siren was published by Brand-New Music (http://www.brand-newmusic.co.jp/artist_ ... _siren.php) and dreamusic (http://dreamusic.co.jp/artist/silent-siren/profile/), they officially went by "Silent Siren" with "サイレント サイレン" (Brand-New Music) and "サイレントサイレン" (dreamusic) on the side for reading assistance. SILENT SIREN is now the bands current name under the label by EMI-RECORDS. (http://www.universal-music.co.jp/silent-siren/)
This song was published under Brand-New Music so the most appropriate Artist to use would be the first one
Artist: Silent Siren
The Katakana is just to assist the reader as shown on the official publisher site so it shouldn't be used (throw in tags). You can see the romanization only being used in the official music video as well: https://www.youtube.com/watch?v=S4i1xbKCK7Y
Your current artist field uses dreamusic's artist choice.
tl;dr, remove the unicode artist and use Silent Siren.
