No you don't have too upload the file to your category. Actually I am going to delete that category since your only going to upload your music.
Login to your account so you can upload your file, then select "Download Area", then select "Submit File", and fill out the information, choose the category you wish to upload your file, and that should be it.
Just make sure that you upload to the correct category that's all. For your music, just upload your music into the Sounds and Music category. If you do happen to upload to the wrong category, just edit the file, and place into the correct category.
Enjoy!
