This has come up a couple of times recently :
http://forum.arcadecontrols.com/index.php?topic=50753.0http://forum.arcadecontrols.com/index.php?topic=50497.0What I was thinking of doing is adding the ability to hit the Down arrow and it selects the first song on the top left album. Then you can arrow down to the one you want.
I did have another idea of an 'album selection mode', where up/down/left/right would highlite one of the 4 albums on screen, then the 'song select' button would bring that album up in full view. Then you'd arrow up/down to the song you want. If you had the one of the albums on the right selected & hit right, I'd scroll the albums. HOWEVER, that is a hell of alot of work to do that and has been on the 'to-do list' for some time now.
Of course, if you wanted you could dedicate 4 of the 6 buttons to F1, F2, F3 & F4 (or map these keys to something else). This brings up the corresponding album in full view. I can't remember off-hand if you can then arrow up/down the list, though, but that is an option that is easy to add
