Hack: wget - unix style

"First, create a text file called mp3_sites.txt, and list URLs of your favorite sources of music online one per line (like http://del.icio.us/tag/system:filetype:mp3 or stereogum.com). Be sure to check out my previous feature on how to find free music on the web for more ideas.

Then use the following Wget command to go out and fetch those MP3's:

wget -r -l1 -H -t1 -nd -N -np -A.mp3 -erobots=off -i mp3_sites.txt
That Wget recipe recursively downloads only MP3 files linked from the sites listed in mp3_sites.txt that are newer than any you've already downloaded. There are a few other specifications in there - like to not create a new directory for every music file, to ignore robots.txt and to not crawl up to the parent directory of a link. Jeff breaks it all down in his original post.

The great thing about this technique is that once this command is scheduled, you get an ever-rotating jukebox of new music Wget fetches for you while you sleep. With a good set of trusted sources, you'll never have to go looking for new music again - Wget will do all the work for you."
