Apple's iTunes Store isn't the only one that has adjusted prices for its digital song downloads recently: Changes are showing up at Amazon's and Wal-Mart's online music stores, too.
Apple Inc., the dominant digital music retailer on the Internet, shifted Tuesday from selling all songs for 99 cents apiece to a tiered pricing model where songs cost 69 cents, 99 cents and $1.29 each. Recording companies are choosing the prices.
Cupertino, Calif.-based Apple also eliminated the copy-protection technology that limited users' abilities to copy and play songs on devices other than Apple's own iPods.
On the same day Apple made its changes, Bentonville, Ark.-based Wal-Mart Stores Inc.'s online music store began selling tunes for $1.24, 94 cents and 64 cents apiece. Previously, they cost 74 cents and 94 cents apiece.
