Try this search link to find music. http://www.oth.net/s/s?q=&cl=1 Eg. Type 'Ennio Morricone' and you should get hundreds of results. Paste ftp address into client. (Have been using this for a long time especially for classical)
If you click on the blue '-' in front of the ftp address you will get their welcome page where you can see what the requirements are (eg. is there a ratio or not).
