Random Numbers with no repeats


#1

1) Give a description of the problem
I have a piston that randomly chooses the number of a list of songs from my DLNA server to play on my speakers. However, sometimes the same song is chosen more than one (in one setting.)

2) What is the expected behaviour?
Piston is working as expected.

3) What is happening/not happening?
I’d like to set up a way (variable?) for the piston to keep track of songs that were played (in a single setting), so they aren’t picked more than once. If I restart the piston, I’d like the list to reset itself.
