I think it does.....
See place of the arrow.
Sorry for the late reply.
What I mean is that there is no repeat feature to repeat just one song. The answer you gave me allows me to loop a whole playlist, but not just one song. Up untill now this is still an issue and I have seen previous threads similar to this with spotify people claiming that it will be in sometime soon. Yet those threads have been posted 2014/2015.
I've found a fix to this issue though. Since spotiffy doesn't have this feature for the Web Player, just use Youtube. When you have a song's video up, just right click the video and click loop.
