Oh man, do yourself a big favor and get a UPS.

I run battery UPS/battery backup/surge units on all my computers.

Not that I need to run the computers when the power is off, but they give you time to shut it down properly and there's no more surges, power interuptions, brown outs, etc.

Edit: BTW, I like that tune. I like all the synth kind of stuff. Your voice is no worse than half the stuff out there on CD. :)
