Here are a dozen or so applets that can perform small tasks on SoundJam, and SoundJam needn't be the front most application or even visible for them to function. I have them in FinderPop, for instance. It tells you the file path of the track currently playing in SoundJam in a dismissable alert-type box. This script requires the free Dialog Director Scripting Addition. This script centers SoundJam's balance control.
Some skins make manipulating balance a little difficult.
Can be set to run unattended. Note that it ignores non-local tracks. This latest version handles larger playlists and is just plain faster. Also allows you to remove the original track being searched. Should no longer crash on some systems.
