Thanks for the quick reply and the great, simple solution. I was thinking modify a temlplate for httpd.conf for VirtualHosts, and changing the document root, but I couldn't find it. Anyhow, this is what I did:
I use DTDNS for DNS, so I went to thier site added mp3. to my host table. 
Then I created mp3.mydomainname.com as a virtual host, and pointed it's content to my MP3 I-Bay.
And that was it. Very simple.
Thanks a lot,
