In late 2015, Rihanna inked a $25 million contract with Samsung that would see her promoting Samsung's Galaxy line of products whilst Samsung would sponsor the release of her eighth studio album and its supporting tour. The Anti World Tour was announced in November 2015 and began in March 2016, with Travis Scott supporting in North America and Big Sean supporting at selected European dates. The Weeknd had also initially planned to support at certain European sites, but he backed out citing "unforeseen changes in upcoming projects". On 28 January 2016, Rihanna released her eighth studio album, "Anti", exclusively through streaming service Tidal. The album peaked at No. 1 on the US "Billboard" 200, becoming Rihanna's second No. 1 and eighth top 10 album on the chart. The album was supported by the release of four singles, including the lead single "Work", featuring Drake, which topped the US "Billboard" Hot 100 chart. Further Platinum-certified singles "Needed Me" and "Love on the Brain" both peaked inside the top 10 of the US Hot 100.
