Dsign Music- Amuro Namie's new song

Dsign Music Website announced (at the right of the second picture)
'Dsign Music have written a new track for the upcoming album.'

One thing that all of you should know is that 'Upcoming Album' may not refer to a full-length studio album.... This is because the U.S. tend to call Japanese singles as albums.

Is it an album or a single?
Can't wait!
but the only thing we can do now is wait...
