So I wrote a script to download (free and legally) some MP3's of a band. The script itself is not all that remarkable but it's handy. With a few modifications it should work for all sorts of stuff really, pictures and such. Just replace the URL with the one you are attempting to get stuff from and the 'mp3' grep with the file extension of the files that you want to download. You will likely need to adjust the sed stuff too. The script just looks at the html on the page, finds all the mp3's, gets rid of the stuff you don't want, then downloads all of it.
wget ``curl http://shinkoyo.com/skeletonstv/dietyofhair/ | grep mp3 | sed s/\<a\ href\=\"//g | sed s/\"\>//g``
