Hi
You will not, as a rule, be able to find your own shared files on your own computer. You should ask a friend to search while you are on line. You could try direct connect and enter your own ip This occasionally works after several tries, but dont count on it!. your ip will be shown if you click direct connect. If it says you have a firewall problem you will need to sort that out. You could post what name to look for (only in the case of original songs) and I or someone else might search for you. I can't right now, I'm afraid. I have to get some sleep
Good luck with the sharing and keep us up to date how you get on
