By "reload" do you mean removing songs that are currently on the shuffle and loading new songs?
If so, the details depend on the shuffle model because the 1st and 2nd gen shuffle is a different from 3rd and 4th gen, regarding how it works. It also depends on how you have been loading the shuffle.
Assuming it's the current 4th gen shuffle (or 3rd gen) AND you have been loading the shuffle manually by dragging songs to the shuffle in iTunes... Select the shuffle in the iTunes sidebar, under DEVICES. If the sidebar (along left side of window) is hidden, from the iTunes menu bar, under View, select Show Sidebar.
Click the small triangle to the left of the shuffle, to drop down the shuffle's content list (indented under the shuffle). Click on Music there. Over to the right, a list of songs currently on the shuffle is shown. From that list, you can select the songs you want to remove, and press Delete on the keyboard. You can select multiple songs at once, or do a Select All if you want to select all songs.
If you have a 1st or 2nd gen shuffle, you have been using automatic syncing (not the manual method) to load the shuffle, or you meant something else by "reload," please post back with more details.
