Go to the FYE Download section, do a search for Tech N9ne and it'll bring up all the available tracks from him and with Everready they have Disc 1 up for DL. BUT, there is a SECOND "Album" besides "Everready (Parental Advisory)", there is "Everready (Transworld Version) (Prarental Advisory)"... there's only ONE track to this version, SLEEPING FRICKIN' BEAUTY! That's the exclusive track. So, this "Code" on the CD is likely just a code to give you a 0.99 Cent credit so you can Download that track.
EDIT: There site is after all, NOT compatible with IE7, I had to roll back my IE back to 6 to get it to work.
