Apple Music is getting its first exclusive song thanks to Pharrell Williams. His new song, “Freedom,” will be available on Apple Music when the streaming music service launches on June 30, the artist announced on Twitter.

No word on how long the song will be an Apple Music exclusive — or whether Pharrell’s upcoming album might be Apple Music only for a limited time. Apple is reportedly negotiating with other artists for exclusive releases.

Apple’s streaming music service launches June 30 for iOS and Mac OS X devices. Android is next, and Apple anticipates attracting 100 million paying subscribers.
