auto/bot music ID3 tag editor

I have a program already designed just needed these added/edited(both windows and mac versions): -make program standalone and automatically change/edit ID3 tags,using a predefined percentage match -ability for program to add/edit album artwork automatically -ability for program to find duplicate files that may be spelled differently but same song using ID3 tags -Program "DESIGN" user interface will need to be remade into a more user-friendly look and feel -program will need added security for licensing purposes(yearly,lifetime,one computer use) Program will need to first ask user which folder/directory to use, once files have been loaded in, user will have a choice of three tools to use,[login to view URL] mislabeled music data 2. Fix Album Artwork 3. Find Duplicates. Once a tool is selected user will be asked certain settings, after settings are chosen and user hits start, program will show current song that is being reviewed and edited as well as a percentage bar of completion and estimated time remaining. After completion of each tool user will be able to review changes that will be made and accept or deny change(s). Program will use 2-3 sources for changes before deciding which change is more accurate(user defined accuracy checker). Please when bidding add >&< to your comment or msg so I know you understand my requirements. Thanks
