NUMBERS TO "DIE" FOR

The Lady Gaga-Bruno Mars duet "Die With a Smile" (Interscope) has spent an astounding 53 days at #1 on Spotify's global Top 50, which, um, seems like a lot of days. The swoony pop-rock tune has earned about 630m global streams on the Spot as of this writing.

"Die," which recently entered the Top 10 at Pop radio, further injected itself into the pop-cultural bloodstream when Gaga joined Bruno to perform it during the very first show at L.A.'s brand-new Intuit Dome.

So, yeah, kind of a big song. Needless to say, the very loud Grammy buzz is giving the artists and their teams plenty to "Smile" about.
