MusicBee is a music manager that is able to provide you with a number of different services. The software is actually free, and for everything that you can do with the program, this is an excellent deal. When you first start using MusicBee, the interface might be a little overwhelming, and you will actually have to download the Lame encoder separately from the program. Some of the pros to using this program is the fact that it allows you to fix tags, find lyrics, and find artwork. It has a built-in CD ripper and format converter, and it is actually compatible with WMP and iTunes libraries.
