The Tidal has turned. Kanye West is once again promoting his pal Jay Z’s new music service Tidal, after making headlines for scrubbing his Twitter account of all references to it. “The love of music is louder than words,” he tweeted Wednesday night. It was a change of tune for Yeezus, considering that he initially deleted all references to Tidal, including removing the service’s logo as his Twitter avatar. West was one of the many music superstars, along with Beyoncé, Rihanna, Madonna and Nicki Minaj, who attended Tidal’s star-studded launch last month, which is why it didn’t go unnoticed when he removed his original tweets promoting the service. It was unclear why the rapper deleted the messages, but the removal did coincide with news of Tidal’s middling launch; it dropped out of iTunes’s Top 700 most-downloaded apps chart this week. Perhaps West’s change of heart has to do with reports that Jay Z and Beyoncé plan to release a joint album exclusively on Tidal, a move that could bolster the flailing company.
