Unrelated songs after one playlist/radio song

[yemainian]

Trying to listen to a Merle Haggard playlist and it plays one song then starts shuffling my son's hip-hop.  I don't mind the hip-hop but don't want it at the moment.  Have tried logging out and back in.  I turned autoplay off and on.  I also tried several playlists and radio stations and got one related song and then back to hip-hop.  Just started today.  Maybe my son changed a setting but I can't find it if he did.

Thanks!
