Tunebite. Is it worth it? What about FU4WM, Soundtaxi and others.

i just recently got a Napster account. i used to have one over a year ago, and used Tunebite. i never paid for it and used the full version. i can't remember if i torrented it or what, it was awhile ago. my question today is: is tunebite worth the $25? personally, it seems like a good idea, but i'm trying to find a program for free to do the same thing. i have vista 32 bit home premium. most of the free progs i've tried do not work. Soundtaxi just errored on every song. FairUse4WM seems like a lot of work, that i'm not sure i can pull off. can someone please suggest something for me, my trial on napster is about to be up and i have to decide if i want to keep it real quick. thank you for any responses and sorry if i sound like a newb, but i'm getting desperate here.
