While at work, i was checking twitter and Dream5 staff released the title of the second track.
It's called Wake Me Up! and it isn't the b-side track, it's the other A-side.
It's also a cover of SPEED's 1997 hit. Here's the PV
And Yes, this single is another double a-side, people.
Also, the mu-mo covers have been released
Next single update will be for profile pics and then a PV preview.
