Jem Aswad Senior Music Editor Amazon Music has announced the launch of two new weekly flagship music series: the hip-hop-focused “Rotation Roundtable” and the Latin/pop culture show “La Semanal Live.” “Rotation Roundtable,” premiering March 15, comprises a hybrid Twitch livestream and 90-minute podcast experience inspired by Amazon Music’s “Rap Rotation” and “R&B Rotation” playlists. It is hosted by journalist and executive producer Speedy Morman, Power 105.1 host/ producer Nyla Symone, “On the Radar” creator Gabe P and veteran journalist Rob Markman. Each episode will feature a “Big Questions” segment meant to incite discourse about current events in hip-hop. The show will also consist of “Hot Takes,” guest interviews, and a debate segment fueled by chat participation.
