Like I said, guys - to be used any way you like!

A song that gets rated as a "3" now, might only be a "1" next week, depending on many, many factors, one of the biggest being the mood you're in.

It is for exactly this reason an easy-to-mark rating system would be useful to me - my tastes change regularly. I can make new playlists this way (and get rid of experiemental tracks).
