Howdy Musical People

Do any of you know of any where online, preferable free, that has aural tests for identifying chord progression? I want some thing like the interval recognition tests, but where you can identify chord progression, and whether the progressions are major or minor.
I'd personally just try figuring songs out by ear. Start with simple acoustic songs and go from there.
And no, Guitar Hero will not help. Even on expert. Really.
ya dude its called Auralia and its made by Sibelius (Avid?), almost all music schools use it, its the best
