Won't shuffle on "shuffle"

[Ray_of_sunshine]

I used to be able to shuffle my playlists, but in the past couple weeks when it says it's shuffled it plays the songs, not in the order that I added, but plays it in the exact same order every single time. I now know exactly what song is about to play. I don't get to hear any other songs since I never get past the ones that always play and I'm getting really frustrated
