Sources tell Pitchfork that Prince’s music will be available on Apple Music, Amazon Music, and iHeartRadio's subscription services very soon, ending a nearly two-year absence of the Purple One’s back catalog from all streaming services besides Tidal. In addition, this morning, advertisements featuring the Spotify logo bathed in purple appeared in the Union Square subway station in Manhattan, as Billboard points out. This seems to hint that Prince’s music will soon return to Spotify as well, adding fuel to recent rumors that the Purple One's back catalog would be widely available on streaming services in time for the Grammys, which take place Sunday, February 12. (Prince's music has been exclusively available to stream on Tidal since July 2015.)

Prince announced a new deal with Warner Music Group in 2014. Representatives for Spotify and Warner Music Group offered no comment on the ads.

Earlier this month, Billboard reported that a Grammy tribute to Prince is rumored to be in the works featuring Rihanna, the Weeknd, and Bruno Mars. The Grammys have not confirmed if this is true.

Last November, Prince’s estate sued Roc Nation for copyright infringement over Tidal's streaming rights to the back catalog.

Correction: An earlier version of this story indicated that Prince's deal with Warner Music took place in 2016. It was actually 2014.
