My 2 favourites have been Stuck On You by Paul Norton (Aussie song which I had to do a bit of digging to locate but it is on youtube) and the tune that sounds like Wont Back Down by Tom Petty and the Heartbreakers. The former was on an episode the other day but haven't heard the latter one recently. I know it's in the episode when Pippa tells Ailsa that she said yes to Michaels proposal (episode 729 or 738 can't remember which). The diner jukebox is definitely one of many reasons why I love The Early Years more than the current show
