If you have Apple’s iTunes 4.2 or lower you will not be able to purchase
or download songs from the iTunes Music Store, but Apple says the new
features in 4.6 are worth the upgrade.

“As of today, customers will need to use one of the three most recent
versions of iTunes - 4.7, 4.6 or 4.5 - to continue purchasing and
downloading songs,” Apple said in a statement given to MacCentral.
“iTunes 4.7 is a free download and includes innovative features such as
iMix, Party Shuffle, CD Insert Printing, and support for the complete
line of iPods including the new iPod Photo.” According to statistics
provided by Apple, the upgrade from version 4.2 affects very few users.

“Less than 5 percent of all iTunes customers are using the old iTunes
4.2 version, so asking them to upgrade to the free iTunes 4.7 is no big
deal,” said Apple. Apple last updated iTunes during last week’s iPod
event with U2 in San Jose, Calif. The main new feature added support for
iPod Photo, which was introduced at the event, but iTunes 4.7 also gives
users the ability to show duplicate songs in the music library. [Continued…]
