"Put another dime in the jukebox, baby" - I Love Rock'n'Roll / Joan Jett
Jukeboxes are fun. Whether they're the old spinning-45's getting-stuck-until-The-Fonz-hits them Wurlitzers or the more modern CD based ones, they give you a feeling of participation. Especially if the bar isn't too full and several people work the jukebox in turn, responding to the other's selections.
And the coolest bits? When the jukebox is entirely digital and has a large MP3 selection, and lets you (for another quarter) download on the spot anything that it doesn't have locally. THAT is cool.
