I apologize for the delayed reply.
I'm not too sure just how long you mean by "for a while now", it's possible that a bit more time is needed for the playlist to be made. Also, as the name implies, the playlist features tracks that you really listen to on a regular with a high replay count. This brings up another possibility, that you've been listening long enough but there's not enough tracks that stand above the others.
If you feel strongly that you've been playing a good number of tracks (around 20 since that's how many tracks are in there) way more than the others and over a long period of time, you can get a friend to send to you a link to their On Repeat playlist or use mine . As far as I know, clicking on this link and links to other personalized playlists should land you in your own playlist. What follows is to like the playlist and add it to your library.
I hope with this info, you can make more sense of the situation and possibly have it resolved soon. If there are any more questions, I'll be right here. Cheers 😄
