How about this - a UPS (Uninterruptible Power Supply) commonly used for 
computers?  Not only do you have your surge and lightning protection, but 
you've got brownout, spike, and AC line noise protection, along with a 
conditioned, steady power supply that keeps going after the power goes out, 
long enough to reach the end of a song.

Has anyone tried this and how big a UPS do you have to get in order to keep 
playing until the song is over?
