[Discover] Discover weekly

[siali]

Hi,

This is not as much idea as it is more of a reflection on my discover weekly playlist. Few months ago I started to follow my discover weekly since the one at the time was very nice and matched with my taste. So since then I have been eagerly wating for Mondays to listen to my Discover Weekly, but surprisingly enough, it is just getting worse. Looking back at the number of songs that I have been saving from the playlists, they have been decreasing dramatically. So, I am just wondering what is the algorithem behind it, how come it is not really following the same trend that it used to?
