Songs from an External Hdd, is it possible?

My external hhd shows up, but none of the songs do. Not sure what is wrong. The Hdd is not formatted to FAT, so that may be the problem. Do I really need to have all my songs on the actual computer, or can djay play off external hdds? Im also running the demo. If I cant play off my External Hdd, then whats the point of paying $50?

You can add songs from any source you want. Just add the folder to the My Mac icon.
