It is good if you care about such things as tags but I organize my pictures/music/videos in a nice directory structure where the name and the position in the tree give me all the information I need so for me tracker is just a major nuisance. For audio there is a wonderful app called symfonie which does exactly what I need but sadly there isn't a good one for pictures and videos AFAIK.

As a general rule, I tend to shy away from apps named after what they've been written in. The name suggests that they are just a practice project to learn programming in so-and-so and once you get to try them, the implementation usually confirms that.
