Kanye West only helped to launch TIDAL back in March, but is the rapper jumping ship already?

The future of the music subscription service looks uncertain after it dropped out of the iOS chart - and West has now deleted a host of tweets about the company.

As well as deleting all mentions of TIDAL from his feed, West has also changed his avatar from a picture of the TIDAL logo to a picture of his My Beautiful Dark Twisted Fantasy artwork.

The deleted tweets included one that said: "Together, we can turn the tide and make music history. Start by turning your profile picture blue #TIDALforALL".

Jay Z bought TIDAL for $56 million in March and relaunched it last month with the support of several artists, including Coldplay, Rihanna, Madonna and Calvin Harris.

Both Rihanna and BeyoncÃ© subsequently chose to debut new material exclusively on TIDAL.

However, following the high profile launch, popularity has dwindled for the service.
