You will probably get a lot of answers. Here's mine:

Install v2.00beta11 immediately, and THEN upload your music.

Install Hijack either before or after the music upload (before is good), and immediately go into the Hijack menu (press and hold knob until it appears) and DISABLE periodic filesystem checking. Otherwise, your music uploads may take even longer.

This is the inverse of more common advice, but the music uploads take forever, and are much slower with v1.03 or v1.03 than with v2.00beta11.
