Hip-hop and R&B offer some of the most fluid, dynamic sounds today, true barometers for where the culture is at and where it’s going. This week, headlining #OnRepeat—a playlist chock-full of the hottest new songs we can’t seem to stop playing—is Rob49’s “WTHELLY”. If you’re not familiar, that’s ‘what the helly?’, a phrase that couldn’t have come at a more appropriate time for hip-hop fans closely monitoring their stock portfolios. Rob49 may not have had Dow Jones or NASDAQ on his mind when he made it, but the smart money is on this new lingo going up. Listen to “WTHELLY” on #OnRepeat, and if you hear something you like, add it to your library.
