Edit ID3 TAGs

At the left you have the mp3s in the current selected directory (To change it use the tree-selection at the top). If you select a file you can see its ID3 TAG at the right. To apply changes click the "save" button.

You may also select multiple files with your left mouse button and then rigth click into the list at the left so that a popup menu appears. Here you have several other options which allow you to perform actions on group of files rather than on whole directories.
