My Question or Issue

 So, I have this playlist of all of my music combined. Whenever I try to play it on shuffle, it keeps repeating a couple of songs randomly (these songs are not in there twice, just once like all other songs). It's not like an issue I used to have where it would only play a small section of the playlist, it now plays all songs but some songs randomly keep repeating to play.
