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 Shoreline Mafia’s “HEAT STICK”, a song that doubles as an endorsement of unity across West Coast hip-hop, reuniting years-estranged Shoreline members Fenix Flexin and OhGeesy. The two sound as locked in as ever across the track, delighting in their shared appreciation for extra-shiny jewellery, heavy artillery and women of all shades and sizes. Listen to “HEAT STICK” on #OnRepeat, and if you hear something you like, add it to your library.
