I found an interesting library today. Java ID3, http://www.dusbabek.org/~garyd/id3/ a useful library to read the tags of mp3 files. I was doing some experiment with music folder today. It helped me a lot. very simple api and fast rendering of tags. Good one! It has some problems while reading UTF based tags. I have written a mail to the enthusiastic developer. Hope he will get back to me!
