Ever want to buy songs off of the iTunes Music Store, but you don’t have a credit card? On Friday, Apple began accepting Paypal as a meathod of payment for its music store, good news for those with checking accounts but not credit cards. Also, Apple will be giving away 5 free songs to the first 500,000 customers to open a new iTunes account in the U.S. using PayPal as their form of payment. That promotion runs through March 31, 2005, or until 500,000 cutomers sign up, whichever is first.
