A few years ago, those programs were incredibly useful. Nowadays, though, there are websites that catalog any number of collections FOR FREE:
Video Games - VGCollect, Darkadia, RFGeneration, and GameTZ
Music - RateYourMusic.com
Films - RateYourMusic.com, FilmAfficianado
Comic Books - StashMyComics.com, comicbookrealm.com
Why pay for this stuff when you can do it for free?
