Spotify is reducing the number of songs played from my playlists

[Stardust5683]

I have a few thousand songs in a few of my playlists.  When I play said lists, the songs played over 3 hours just repeat, instead of playing all songs within the list before repeating them.  This is annoying as I need to shuffle the songs myself every 3 hours in order to hear a larger variety in my play list. 

Suck when you are having a party and the songs start to repeat!!!!
