The new version of Sonic Stage, Sony's digital music management software will support the AAC audio format for Apple. Sony has already supported AAC format in its PSP gaming device and some mobile phones and is going to enlarge the use of AAC format to Walkman digital music players. Sonic Stage can play music encoded with iTunes in AAC format, but can not play copy-protected songs from the iTunes Music Store. One report on Sony's announcement claims that "Sony's latest strategy is taken as an open acknowledgment that it can no longer ignore iPod's dominant lead."
