Rihanna's at it again dropping another hot track! "Diamonds" debuted on Billboard's Hot 100 at #16 and is bound to climb to the top of the chart. There's already tons of remixes out there but my favorite by Shahaf Moran is featured in my cycling classes this week! The audio version is below. Also, congrats to Rihanna for being named Billboard's #1 Pop Artist from 1992-2012 ...and she's only been at it for 7 years!
