Kanye West once vowed to never bring his latest album "The Life Of Pablo" to anything other than Tidal, but one of the album's most talked about tracks just landed on some other streaming services.

On Sunday night, the rapper's hit song "Famous," which features vocals from Rihanna, showed up on Apple Music and Spotify. These two streaming companies are rivals to Jay-Z's Tidal, and even though it was only one track and not the entire album, this goes against exactly what Yeezy promised he wouldn't do.

"My album will never never never be on Apple," he tweeted in February. "And it will never be for sale...You can only get it on Tidal."

"The Life Of Pablo" debuted on Tidal last month and even though "Famous" is not available for purchase on iTunes, it can now be streamed to all subscribers of either of these services. This has everyone wondering if his Tidal-exclusive album will soon be available to those who don't have a Tidal subscription, or if this is the only track that's getting special treatment. He also recently announced that he will no longer be putting out physical CDs. "I was thinking about not making CDs ever again...Only streaming," he tweeted earlier this month. "uuuuuum, so there it is...No more CDs from me."

West caused quite the controversy when his album first came out and people quickly realized the song "Famous" was a diss-track to Taylor Swift, who he used to have beef with.

"I feel like me and Taylor might still have sex. Why? I made that b---h famous," West raps on the track.

In 2009, he famously interrupted the 26-year-old "Bad Blood" singer's acceptance speech at the MTV Music Video Awards, but the two squashed their beef when he apologized to her after she presented him with the Video Vanguard Award at the 2015 VMAs.

Despite the fact that they had worked out their differences, Swift's squad was not pleased with the lyric and several of her friends, including her brother, took to social media to slam West. He quickly went on another Twitter rant to explain that he and Swift had spoken about the lyric, even though her rep had denied that this ever happened.

"I did not diss Taylor Swift and I've never dissed her," he tweeted. "First thing is I'm an artist and as an artist I will express how I feel with no censorship...2nd thing I asked my wife for her blessings and she was cool with it...3rd thing I called Taylor and had an hour long convo with her about the line and she thought it was funny and gave her blessing...I'm not even gone take credit for the idea...It's actually something Taylor came up with."
