The Jam Station
Located top right corner in a red banner with 6 icons. Between the Music Staff (Scale Finder) and the Metronome Icon
Just roll your curser over it.. It will say Jam Station. Click to start.
Select your genre, when the Jam starts you can click on view lesson that goes with the Jam..
I don't know if there is a directory to get what song your working on. other then scrolling throught it. I've always worked right from the lesson.
Hope this was what yoiu where looking for.
