Where does Snow Leopard store iTunes Music

Greetings,

I wanted to get a clean start for my iTunes Library.

First, I deleted my iTunes folder in Documents into the trash and then emptied the Trash. Second, I deleted the iTunes app.

I went to iTunes and downloaded a new iTunes application. After it was installed the entire iTunes music library was there when I opened my new download of the iTunes Application.

Where did it come from if I deleted my iTunes folder thinking I was deleting all of my downloaded songs?

So my question is where does Snow Leopard store these songs? I assumed they would be gone so I could begin to put in new albums in my iTunes.

Thanks in advance for your help and support.

Leigh
