To get a clean download, if you knows the file format you want, you can do this:
wget -nd -r -l1 --no-parent -A.mp3 -A.wma http://www.foo.com/mp3/
To explain briefly the options speficied;
-nd no directory, by default wget creates a dir
-r recursively download
-l1 (L one) level 1, download only of that particular folder, don’t go in depth on it.
–no-parent I definately don’t want the parent’s files
-A The -A option allows you to specify which types of accepted files should be downloaded. In this case, all files with the .wma and .mp3 file extension will be downloaded.
