romanised artist: Yakushimaru Etsuko Metro Orchestra
(ranked artist was wrong for this specific song but the other maps use ^ and the song is credited as such, not just yakushimaru etsuko)
title: 少年よ我に帰れ
romanised title: Shounen yo Ware ni Kaere
(ranked consistency for the title ^)

tags: boys, come back to me mawaru penguindrum mawaru-penguindrum metropolitan anime japanese pop rock jpop j-pop jrock j-rock opening full version RADIO ONSEN EUTOPIA
can also add live ver version to tags since this was on the radio but no resources indicate that (Live Ver.) should be in tags
metro orchestra is not the artist of this version so the current artist is fine
on the title romanization though, shouldn't it be Shounen yo Waga ni Kaere ? i tried transliterating into hepburn several times and it never outputs Ware. im not sure so i leave it up to you but if you do change id keep ware in tags just because it is widely used
