If you have an older PC, you might find new versions of iTunes and Windows live player make your computer work pretty hard. Snow Player is a simple media player that won't eat up your system resources.
Istallation is really easy, although the first time you run it it will ask you about signing in for online functions. Registration is free but we have yet to be able to sign into Snow Player with an account. Despite that problem, as a simple player Snow Player works fine. There is a small control module, and a box to drag in files to be in your playlist.
You can save playlists for later use, and also import folders. However, Snow Player won't play multiple folders. Bigger applications have much more intuitive library systems. Snow Player also features an equalizer, but it is one of the worst you will find, as increasing any of the values will lead to horrible sound distortion. It also claims to play video files, but it failed to do so in our tests.
If you are looking for a simple, lighweight media player, VLC player is much, much better. With VLC everything works well, while too many features of Snow Player are broken.
