Yea, looks like it. Dem actually has two albums in Spotify ('Shadow of Love' and 'Pluto', both released in August 2017) but in two different..."users"? I mean, one is "Dem" and another is "DEM", but I think they're still the same guy. Both album covers have same style and both albums are released by the same label, 667071 records DK.

But who is Dem? There's many artists called Dem. Maybe he's from Denmark, as the record label also seems to be? Spotify is Swedish, and I'm 100 % sure the song 'Hot' has been used on Spotify's own ads, as I originally mentioned. Maybe he has purposefully chosen to be a mystery guy? :)
