Sorry, but I think you're stuck with the Memory and Imagination combo. Basically, you think of a tune, modify it with Imagination and then play it back later using Memory.
Legally, you should be using similar techniques for your OS.
We do NOT tolerate pirating here at MacRumors. Both of the operating systems that have run/running on your Mac have been illegal copies, aka you do NOT have a legal single license for your computer.
It's only what, $70 for iLife '06? I mean, ****. You've already pirated $260 worth of OS's atleast (each OS costs $129)
