As part of a new agreement with the NBA and a startup called UnitedMasters, Apple is curating a weekly playlist called BASE:LINE. It will feature songs from up-and-coming independent hip-hop artists picked by Apple Music director Ebro Darden. The NBA will soundtrack highlights its shares online with songs directly from BASE:LINE.

This week, you’ll find music from rappers like KOTA the Friend and Princess Nokia, to name a few. A lot of songs come from artists who use the UnitedMasters app to share their music. The startup was founded in 2017 by former Interscope Records president Steve Stoute. The app allows musicians to upload their songs to platforms like Apple Music and Spotify without the help of a traditional record label.

Whether BASE:LINE represents a new approach for Apple or a mere one-off is hard to say at the moment, but it seems clear playlists will be one of the ways music streaming services continue to differentiate themselves moving forward.
