PowerSearch is a very useful and powerful feature. It takes your Query from the Digitrad and lets you extend it to many different Web sites and indexes. It can be used to find lyrics or tunes not in the Digitrad, or to find Real Audio or Mp3's of songs you do find in the Digitrad. Many of the options included are very useful, so try them out and figure out which ones are best for your purposes. Items marked with $ means that the Mudcat gets a percentage of sales through that link.
