Just to throw it out, if you have your music on a Media Card and you encrypt the media files there is a bit of a delay for the BlackBerry to access the files, program works pretty fast for me (of course I just use the shortcuts at this point )

I converted all my songs to .mp3 format and it still does skip forward to the next song, it happens pretty randomly I could go a day without it skipping and the next day it will skip every other song.
