Well, if this is your own music that you've created, then you can use a FTP program, that is if Dreamweaver hasn't got that built in already, like SMART FTP (Google search on that). You simple login to the site as you would with Dreamweaver... domain, username and password. With that program you can drag and drop any file... music, doc, jpg, etc on to your webhost and it will then upload. Whichever folder you chose to put the file in, that's where it will be on your site. Then you can simply link to it from the site, or you can put a media player on your site.
