download your demo of BPM Studio here to test it:

http://home.t-online.de/home/alcatech/bpmdemo.exe

This is the homepage of BPM Studio. It's a program for mixing MP3's
http://www.bpmstudio.com/html/index.php

This is the homepageof PCDJ. It's the same type of program
http://www.pcdj.com/download.asp?transaction_type=2000


They both use ID3 tags, so it must be possible, I think

Is there any software that can read from BPMStudio or PCDJ what song is playing? You have winamp plugins, but I dont know any program that can read from this software.
