Apple’s music social network, Ping, has gotten a big boost from a major social network, namely Twitter. Twitter has confirmed via a blog post that users of Ping and Twitter will be able to link their accounts from within iTunes and once that is done, they will be able to alert their followers of songs, artists or albums that they like or review. The tweets can include playable song previews and links to purchase and download music from iTunes. The new feature is available in all 23 countries where Apple’s iTunes Music Store is offered.
