If you're trying to stir up some Christmas spirit then I recommend you take a look - or rather a listen - at Christmas Sounds.
This is a collection of 16 different festive noises and music, all available to play by clicking on an icon. Each icon is decorated with a fun seasonal image that represents the audio hidden behind it.
There's a pretty diverse arrange of audio in Christmas Sounds. Highlights include a music box version of Silent Night, the peel of church bells, and the sound of a roaring log fire that will instantly warm you up on a cold winter's day. There are some sounds that aren't quite so good, notably the grating sound of sticky tape in the 'Wrapping' effect. The two Santa sounds are in effect exactly the same, it's just that one has sleigh bells in the background.
Christmas Sounds will certainly put you in the festive mood. One major drawback though is that you can't set the audio as a ringtone or alert sound.
