ATLiens and Wheelz of Steel are both songs off Outkast's 2nd album, titled "ATLiens". The single, "ATLiens", has a great unworldly-sounding beat with a great hook and some super-crafty wordplay by Big Boi in the 1st verse. "Wheelz of Steel" is another great track with tag-team rhymes by Big Boi and Dre and some great scratching in the chorus. Outkast has grown lyrically since "Southernplayalisticadillacmuzik" by listening to these two songs, and it definitely shows.
