Split your music into thirds (or quarters), and let it upload while you sleep.

Low-tech, but it's simple.

(On a side note, if you think it takes a long time via USB or ethernet, you should try doing it by serial cable... I uploaded one song that way just for giggles. It brought back memories of downloading things from a BBS.)
