When Sam Flynn enters his father's arcade, and restores power to the machines for the first time in 20 years, the jukebox immediately starts playing Journey's "Separate Ways". (When he's going down the hidden staircase, it's moved on to the Eurythmics' "Sweet Dreams (Are Made Of This)". But, like the other machines, it hasn't had any power for 20 years; and unlike video games, juke boxes don't have any demo mode. So even if it's on free play, any remaining selections it had when it last had power would long since have been lost. Sam didn't make those selections; who did?
