The RandomMix plugin currently takes no steps to avoid playing the same
track more than once. However, I've started work on a change to stop
songs being played more than once using the last played timestamp
(http://bugs.slimdevices.com/show_bug.cgi?id=2551). This will get
done, but I'm still recovering from the Christmas period atm so am
spending very little time on Slim stuff.
