I have noticed that they really scaled this back from before when they played a lot of artists that they never played during the week. They are basically playing the same songs on their playlist, unless someone requests a song. If that is the case, why even have this on Sundays. They pretty much play like 7-8 80s an hour weekdays. I do not think the ratings are calculated on Sundays. I know David Eduardo would know this for sure. The only thing I could think is just to promote that they play the most 80s. If it was me, I would play more variety on Sundays. Then they could slowly incorporate some of these songs into their playlist.
