People have been reading between the lines, or at least between the subway posts in New York, saying that Prince's catalog will be making a comeback on popular music streaming services in time for the Grammys on February 12. Currently, Tidal has exclusive streaming rights to the Purple One's back catalog. Speculation started when Spotify started posting very coy billboards in high-foot traffic areas like the Union Square in New York. And by coy, they're just posts painted in purple with Spotify's logo on them. If there is any truth to the rumor, Prince's catalog is expected to hit Spotify, Apple Music, Amazon Unlimited, Deezer, and Pandora.
