The artists who still aren't on iTunes

The Beatles may have signed up to iTunes, but still missing are . . . ▶ AC/DC - The makers of the second bestselling album in history, Back in Black, refuse to make their tracks available individually. ▶ Jay-Z - Most of the rapper's work is available, but not his American Gangster album: "this collection will not be sold as individual singles." ▶ Frank Zappa - The Zappa catalogue was removed from iTunes by his widow. ▶ Kid Rock - Because there are no packaging or distrubution costs on iTunes, argues the US rock-rap crossover star, artists should get a much higher royalty.
