OK, Now I'm curious ... I do the same test with several hundred MP3's on my Win2k box and i barely jump up memory usage ... Hmm... Any particularly large individual files? I don't think that matters, just curious ... Everything should be stream-based, so I can't imagine what could be going on.

Grab http://www.batmanthehorse.com/jemplode/jemplode20.jar and try it out for me .. This is using a different MP3 tag parser library.
