Ah, well nevermind it then. The first (faster) version was faster because it was buggy.. didn't actually work correctly.

For the amnesia, my player went back to normal when I reloaded stock Hijack onto it, and then selected a small playlist from the menu, put player into standby, powered off a few seconds later, and rebooted.

If yours persists in forgetting about it's playlist, then I'd suggest a wipe of the dynamic data partition should cure it; somewhat extreme, I know, but if it persists..

Cheers
