The Juke box sounds great since your adjustment of the whatchacallits, but last night it went into a mode where it jumps from track to track randomly, never playing a complete album. If I put a play list of several albums on, it will play one track, then randomly jump to another track in the middle of another album aso aso. If I put on one album, same thing - jumping from track to track.

What's up with that?

Not broken, feature. Some people like random selection.

There is an icon on the media player screen which toggles Random/Sequential play.

In the media player on my notebook, here are the Random and Repeat toggles :

On another computer, it's actually a 4-way toggle in one button:

Your icon(s) may look different. You should also be able to toggle the Random state using the Menu Bar. Right-click the Title Bar, then select the Play Menu. Repeat and Shuffle (or words similar) are options available to toggle.

Lastly, you can use hot-keys. Ctrl-H will toggle Shuffling. Ctrl-T will toggle Repeat.
