How do I delete music from my PB? I also discovered that on my desktop manager under the music tab there are several duplicate songs that I wish to get rid of. My music is stored on a separate hard drive on my computer and there is music on that drive that does not show up in desktop manager as well, how do I get those music files to show up in desktop manager?

I can't answer your question directly.
I prefer to drag and drop files rather then use the sync feature of any program because of the problems you describe. You can plug in via USB and open the PB folder just like any drive. Go into your music folder and delete the songs you don't need. You can also set up the wifi transfer to do the same with the cable.

Any file manager, including ours, will let you delete files from your PlayBook.
