A lot of people are going loopy over this method for downloading mp3s that Jeffrey Veen posted. Basically it's a command line protocol that will allow you to download all of the mp3s a website links without having to actually go to the website manually.
So you point this sucker at randomMP3blog.com and it looks at all the links and downloads all the .mp3 files in one quick swoop. You can even program it to go to 30 CDs every day, scrape the songs, and catalog them on your computer.
Okay, that's sort of cool. Kinda. But I think it totally misses the point of all the sites who are taking the time to actually find these mp3s. The people running these blogs take a lot of time out to write about the songs, catalog them, and sometimes even host them on their own sites. By doing this, you're just blindly downloading everything without knowing the back story.
If that's the case, why don't you just load up a P2P program and download everything you can find? It serves the same purpose. Save the bandwidth for people who actually want the mp3s.
Or take it one step further. Create a program that automatically buys everything someone links to from Amazon.com. You can have your credit card and shipping information automatically in your account for quick ordering!!!
