The one copy song was a track released in such a way that only one person at a time could take a listen to it. Adam Tensta remembers back in the day when one had to wait for a sing to release, and one had to stand in line to get a new single fresh hot off the presses. With the one copy song, some of that exclusivity was recreated, whilst shamelessly using peoples need to get first in line by asking them to watch something, tell fifteen people on FB about this, or tweet 15 friends about it to spread the song further.
