Depending on whose watch we’re going by, Frank Ocean has either been M.I.A. for roughly four years or the four days since he walked off his livestream late last Thursday night, leaving the world to watch paint dry in his absence. Will we eventually have to consider filing a missing person report? Eh. For now, here’s “Lean On” singer MØ fittingly covering Ocean’s Channel Orange song “Lost,” so we can all remember an increasingly distant time when the man made music, rather than rectangular wooden boxes. In case you’ve forgotten, no, the original was not the reggae-synth experiment MØ’s attempted, or … was it? Our memory’s fading fast, Frank.
