Right click on the selected files, click on "edit ID tag", window should open where you can change the genre to Christmas. Close Windows Explorer and you should be done.
An alternative tag editor is "mp3tag" Don't be fooled, it edits tags on just about any audio file, wave, flac, m4a, etc, as well as mp3. But the right click contextual tag editing (which is a part of dBpoweramp) is very good for simple tag edits like what you need.
