We don't know when Babymetal are releasing a new album, but the songs keep coming as the kawaii metal group has debuted the aggressive "Pa Pa Ya!!" featuring Thai rapper F.Hero.

If you've struggled to define Babymetal's sound in the past, "Pa Pa Ya!!" won't make it easier. They've always pulled from a grab bag of influences, retaining their metal foundation regardless of the J-pop and electronic shimmer. The opening sets the tone for one of Babymetal's heavier songs with the title screamed through distorted vocal filters and at the halfway mark, "Pa Pa Ya!!" plays host to the gravel-throated rapper F.Hero with horror-esque synths countering the bubblegum chorus.

Listen to "Pa Pa Ya!!" below.

The song is bundled as a recent release alongside Babymetal's past three singles ("Elevator Girl," "Distortion" and "Starlight") on Spotify, possibly indicating that this collection of tracks may not be part of the new record.

Earlier this year, the Japanese idol group revealed that their third full length record would arrive sometime in 2019. The new release will be Babymetal's first since the departure of Yuimetal, who formally resigned last October. In her statement, she revealed her physical condition is not conducive to touring and that she intends to move forward with her musical career as Mizuno Yui.

In conjunction with Yuimetal's statement, Babymetal unleashed "Starlight," the first song without their longtime co-frontwoman.
