karaoke versions give you the backing tracks though some with backing vocals! no lead tune with it
as odd as it sounds dawny look for cheap cds in bargain shops, like piano classics or pan pipe moods etc etc or saxophone stuff, most of them are songs that you know and can get really cheap
if its backing tracks you are after then pm me i have a back catalogue of about 4000 tracks all just music, some with backing vocals but alot of them just music
