Why won't 8 tracks let me replay the mix?

Oh how wonderful a world to have something like 8tracks.com HOWEVER every time I get to the end of a mix it won’t let me restart the mix anymore. Am I just missing the button?? I used to be able to just refresh the page and the songs would shuffle and all replay but now I can only get the last song in the mix to play and then it switches to another mix. HELP!
