BABYMETAL, who celebrate ten years since their formation this year, will release a best-of album titled "10 BABYMETAL YEARS" on December 23. 

The best-of album will be available for purchase in ten different types: Regular Edition (CD or Vinyl), Limited Editions A ~ C, THE ONE Editions A & B (for members of THE ONE only), SU-METAL Edition, MOAMETAL Edition, KOBAMETAL Edition, and X Edition (different release date). Limited Edition A will come with a Blu-ray disc containing music videos for 15 songs, while Limited Edition B will come with ten different jacket covers that will reflect the ten years of SU-METAL (Vo, Dance) and MOAMETAL's (Scream, Dance) activities. 

THE ONE Edition A will enclose a "karuta battle set" consisting of a battle card, battle CD, and battlefield (picnic sheet). Meanwhile, THE ONE Edition B will be a set including two Blu-ray discs, a 72-page photo book, and a big flag. Both THE ONE Editions will come with special packaging. 

Consisting of ten songs selected by the BABYMETAL and producer KOBAMETAL, the SU-METAL Edition, MOAMETAL Edition, and KOBAMETAL Editions, will not be for sale. There will be a “prophet card” with a serial number enclosed at random in the Regular Edition, Limited Editions, and THE ONE Editions. Using this card as an entry ticket, only those who predict the track list and song order correctly for three types will be able to obtain them.

As for the X Edition, BABYMETAL have only revealed that “ONLY THE FOX GOD KNOWS.” The release date and other details for this will be announced later.
