One thought process when you dream about a jukebox is that you are a decisive person, especially when you have the pressure of others being present while you make your choice.
It might also indicate the control you have over your life when something isn't going your way or when you feel the need to do something different- you go out and get it. Or simply the control you have over your emotions.
If someone else was picking the tunes on the jukebox, this might be your subconscious telling you that someone else is taking the reins in your life and you need to take the control back.
Pay attention to how you felt in the dream. If you were happy it's possible that something good is about to come your way or you are reflecting on happy times in your waking life. If you felt sad, maybe something negative from your past is still haunting you and you need to find a way of letting it go.
If the song was fast paced- perhaps you need to have more fun during your waking hours- if things have been too serious lately- it might be time to listen to some music that makes you feel like getting up and dancing.
If the song was slow- maybe you need to take things down a notch or two if you haven't been able to keep up with your pace of life lately.
If you chose a song on the jukebox and something else came on instead it might be time to examine your wants vs your needs as the two might not be in line with one another.
