Spotify CLASSICs is continuing to celebrate catalog music. The program has released its second chapter, which highlights the 100 greatest R&B songs of the streaming era (2015 to present day). The criteria used to make the list includes quality, impact, replay value, influence and cultural significance; it's based on the "cultural and musical expertise" of Spotify's U.S. editorial team and Head of Urban Music at Spotify Carl Chery.
