Given "Weird Al" Yankovic's musical preoccupation with popular cultural pheonomena and with Americans' weird purchasing habits (see also: "Ebay," "Mr. Popeil," "Buy Me A Condo," and "Hardware Store"), it was probably just a matter of time until he wrote a song about Craigslist. According to the timestamp, his new video was posted to YouTube a couple of days ago, but given that it only had about a hundred views when we checked it out — meaning that his vast legions of fans hadn't found it yet — it apparently just went live. And the song, "Craigslist," became available at Amazon at midnight. Both the song and the video are also available on iTunes.
