was thinking how would you shuffle some LPs and closest I can think is the daft players you used to get where you could cue them up and once one was finished the next one would drop down on top of the previous one. tapes, well they're easy. stick the radio on turn the volume down then slap a blank cassette in and hit record for 3-5 minutes, pause for a bit then repeat process till tapes done.
mibbis best just listening tae the radio right enough.
