From the developer:
eTunes is a music organization program written by Eric Zhang in the Windows API. The code is entirely writen in true Visual Basic .NET and OOP (Object Oriented Programming) with a few exceptions to the OOP part here and there.
The purpose of eTunes is to provide a simple and intuitive interface for anyone to organize their music files, specifically mp3's.
