I’m kind of a regular at Bagel Street Cafe in Södermalm, Stockholm (I’m actually the mayor of this place 
), which obviously means I enjoy their bagels and coffee a lot, let alone their friendly service (enough with the free promotion).
Today I just experienced an unintentional add-on service which could be rooted back in the jukebox era. They share an open playlist on Spotify where anyone can contribute. What happened was that when I just commented on the music played at the time, the girls at the counter told me they would gladly played anything I had contributed on their shared playlist, and so they did! (They also provide free wifi)
In other words, just how a jukebox used to work, customers can choose music right on the spot. The best part is that being Spotify based, all you need is a laptop/notebook/.. or phone and you can choose any music you like and added to their playlist (Spotify required of course).
Spotisquare
So next time you sit on a cafe check if they have a Spotify playlist, (e.g. Spotisquare is perfect for this) and go ahead add your tunes and I’m pretty sure they’ll gladly play it for you
