4johnny:

Not exactly sure what you're after here, and need a bit of clarification. First, what version of BIAB are you using?

There are a couple of different ways to get at the Jukebox function. If you open a "new" song in BIAB (2014), and click on the "Jukebox" icon, you get the "Options for Jukebox" window.

Near the bottom is a "Change Directory" button.
If you use that, you can navigate to any folder in your system containing BIAB songs. Once you choose the folder and click the "Play Jukebox" button, it will play through the songs in that folder.

If you want the Jukebox to play another song, simply add it to that folder.

The second way to "juke" songs is to use the "Song" button (bottom half) and select "Favorite Songs". In that window you can use the "Load Set" button if you already have a "set" of favorites saved.

Then you use the "Insert" or "Append" buttons to navigate to the song you want, and to add it to the list.

If you DON'T have an existing "set" (i.e. a .FSO file), then start with this window and build a set from here.

In either case, you then use the "Juke" button in this window to play your songs.

Let us know if I haven't answered your question.
Give us some more info and we'll get to the bottom of it.

Good Luck!
