I am planning to do it as win32 based application. Initial screen shows a folder browser so that user can select the Disk/Folder/sub-folder in which the application search for the .mp3 file. Application will list the findings as and when it finds a mp3 file in the selected location. The searched files are put in list box with path, size, author and other required music file informations. The search will enumerate through all the sub-folders inside the selected path.
Code review is done at the completion of the application and comments will be added in the required places for improving code understandability.
I am confident in doing this job as i have the experience in all the above explained controls.
