Kanye West releases track on Apple Music despite vow

Fans can now listen to Kanye West's song Famous on music streaming platforms other than Tidal.

Famous, which features vocals from Rihanna and lyrics that controversially reference Taylor Swift, is the first track from Kanye's Tidal-exclusive album Life of Pablo to migrate to competing subscription-based streaming service Spotify, as well as Apple Music and GooglePlay Music.

According to music magazine NME, Kanye has also tweaked the tune to include a Nina Simone sample, with the original line "she be Puerto Rican day parade wavin'" also swapped for new lyric "she in school to be a real estate agent".

The 38-year-old rapper did not announce the track's wider release on social media websites and has yet to confirm if any other tracks from The Life of Pablo will be added to streaming services other than Tidal.

It is an interesting move for Kanye, who previously wrote on Twitter that his latest album would "never never never be on Apple".

Tidal, which is owned by rapper Jay Z and a variety of other music stars, has recently extended their free three-day sign up period to enable fans to listen to the album, which it has streamed solely since it dropped in February (16).

Kanye, who is rumored to be planning a tour, marked Easter Sunday (27Mar16) by sharing a new version of the track Ultralight Beam titled Ultralight Prayer.

Taking advantage of the original's gospel elements, Kanye has tweaked the track's lyrics to include the lines "Let them know that's why you took the nail; so we could have eternal life," and "you will forgive all of our wrongs and make us new again".

Kanye posted about the new version on his Twitter page earlier in the day, simply posting a link to the track and writing: "Happy Easter!"
