Inspired by Homer Simpson's insipid (yet catchy) method of avoiding phone callers, my latest iTunes music store purchase is
Wichita Lineman
by Dwight Yoakam. To avoid confronting someone on the phone, Homer pretended to be an automated phone system and he sung Wichita Lineman as the background music.

That's one code down, 23 more free songs to be redeemed. I've got two more caps at home waiting to be registered so I can buy 18 more Pepsi colas before the 31st.
