According to recent reports Apple is about to raise the price for premium songs at iTunes starting April 7. Until now, Apple has charged a simple $.99 per tune but they are about to break the $1 barrier and test the waters at $1.29. The LA Times reported it like this:

"The world's largest music store, Apple's iTunes, plans to boost the price of many hit singles and selected classic tracks to $1.29 on April 7, breaking the psychological barrier of 99 cents in what could be the first big test of how much consumers are willing to pay to download individual songs."

Apple has not officially announced the change but they've been notifying record companies of the upcoming change.
