Blog plugin for winamp

ok.. more of a code question. In the instructions of this plugin it tells me this

Add the function ‘now_playing_div()’ to your pages where you want
to display the song info.

this would be in the sidebar… my question is what do i surround ‘now_playing_div()’ with? What’s the code I wrap around that to make it show up? It wasn’t specified in the readme and I’m confused.
