Yamaha DTXpress/DTXplorer/DTXtreme

Hi all,

Just joined the group after reading how darned helpful you all are!  
Wish I would have found you months ago!  At least I now know what 
headphones to buy to take care of my volume problem, but I do have 
something else I am needing help with..... 

I am looking at either trying to find a audio software program that 
can take the drum track out of a downloaded or converted mp3 or wav 
song file...something realitivily inexpensive would be great!!  

or.........

Is there a website where a person can download tunes to play along to 
that already have the drum track removed?  I have found one, it's:

http://216.103.111.115/perl/drums/index.cgi?WebPage=jamtracks

but, there are only two songs there.....at least you'll get the jist 
of what I am looking for.

Thanks ever so ~ I am really getting tired of the songs that came 
with the DTXpress! :)
