R&B is one of the most dynamic, adventurous sounds in modern music, a place where art both personal and provocative meets the mainstream. From the alt vanguard to modern vets, straightforward to left-field, these tracks capture where R&B is now and point the way to where it’s going. At the top of this week’s playlist is Summer Walker’s “No” from her newly released album Finally Over It. We update this playlist regularly. If you like a track, add it to your library.
