A re-cut by producer Martignetti that was not on the EP premiered on the blog Stoney Roads, who noted the song to be fitting in an episode of the HBO series Girls. A remix by house producer Claude VonStroke was released on Februby Spin magazine, which journalist Chris Martins named a 'demented dance-floor delight.' A day later, Vice Media's channel Noisey released a remix by New York City-based duo Solidisco, advertised to 'make you nostalgic for the long weekend just gone (thanks President's Day!), but super happy because Friday is just a little bit closer than it should be.' Both re-workings were part of the song's remix EP that also featured remixes from Fred Falke, Thomas Newson and Viceroy.

Records premiered the final mix of 'Ghost' for streaming on December 10, 2013, and the song became available in digital stores by January 31, 2014. Colin Leonard mastered the track at SING Mastering in Atlanta using SING Technology. The moment I wrote it, I thought, 'Wow, this could really be something.' Written and produced by Dubuc, the original mix that appears on Mystery Skulls' debut album Forever was mixed by Jeremy Wheatley for 365 Artists at 4db Studios in London, with Adam Looker assisting. The concept of the song is sung in the hook 'This time I might just disappear.' He described it as 'really special song. 'Ghost' is about wanting to 'disappear completely and start over' again, as it was inspired by Dubuc relocating from Dallas to Los Angeles without letting anyone know. 'Ghost' is a four-minute, eighteen-second song described by Vibe as an 'electro retro funk' track with harmonies influenced from disco. The song was also very well received from music critics. However, a second, animated music video for the song, which garnered over two million views in less than a month, helped put the track in the top 20 of the American Billboard Dance/Electronic Songs chart.

The official music video for the track, directed by Josh Thomas, was released in February 2014 by Vice Media's electronic music channel Thump.

Records as the lead single off the project's debut album Forever described as an electro retro funk track, written, produced and performed by Dubuc, is about him wanting to 'disappear completely and start over' after he didn't let anyone know about him moving from Dallas to Los Angeles, as reflected in the song's chorus. ' Ghost' is a song written, recorded, produced and performed by American musician Luis Dubuc for his solo project Mystery Skulls.
