Bruno Mars is the secret ingredient on the two biggest songs in the DSP world, sitting atop Spotify's global Top 50 with ROSÉ's "APT." (Atlantic) at #1 and the Lady Gaga collaboration "Die With a Smile" (Interscope) at #2. Atlantic megastar Bruno lends his impeccable vocals to both tracks and his rock-star energy to their respective videos.

We note that "APT." is nearing the half-billion mark in global streams on the platform, while "Die With a Smile" is well past the billion mark.

Bruno and ROSÉ earned big international press for their lively performance of "APT." at Japan's Mama Awards on 11/21; check it out below. The BLACKPINK star's solo album rosie is due on 12/6. Have the two artists "rewritten the K-pop playbook?" Some really smart people think so.

Much chatter surrounds a likely Bruno album and tour next year. Stay tuned.
