Chrono Trigger arrangement by Shota Shimizu

[viaan]

I've got a question that bothers me for days now and I don't know what to do v_v

In 2009 Japanese artist Shota Shimizu released a single called 美しき日々よ / さよならはいつも側 (Utsukushiki Hibi yo / Sayonara wa Itsumo Soba ni). Track three on this single is a modern pop version of Chrono Trigger's 風の憧憬 with lyrics.

Should this be added to the database and how do I tag this?
It's not an official promo, instead I would call it a fanwork even though we got a celebrity perform the song.
