You probably have done this as you noted it in the subject, but i
didn't see it in the code. Although prefs is used throughout the
entire documentation, it is not actually a global variable in the
gadget environment. It is an instance of the _IG_Prefs class.
var prefs = new _IG_Prefs(); // as noted you probably know this but
just covering the bases.
Where I think your real problem lies is in the prefs.setArray
execution. It is expecting to receive the entire array, where you're
iterating over that array and sticking each item inside, this is in
essence overwriting the last value each iteration, not to mention the
fact that its the wrong data type, its expecting an array.
prefs.setArray("songArray", songArr);
