Actually, the sticky is there for a reason.
Most of these free sites don't work properly with all operating systems. (like mine). Meaning that you guys can post links to your freebie sites until the cows come home, and I won't be able to listen to your MP3's.
Not to mention the fact that it's a royal pain in the butt having to register or surf through multiple pages just to listen to something.

If you want your stuff to be taken seriously, get a web hosting service. For instance, I'm signed up with these guys.
It's like, $3 a month and you get 5 GB of space to put your MP3's or videos or pics or whatever you want...

Then you just post a direct link to them like this:
http://s93744050.onlinehome.us/mp3/Rocksplosion.mp3

People can listen to your MP3's without having to surf through a crapload of pages.
Plus you can post high quality sound files of the lo-fi mp3's most of these free places require ya to use.
