On Ping users can easily link to their Twitter account to instantly find Ping users among the people you already follow on Twitter.
Once they?ve linked the accounts, whenever they Post, Like, Review, or tell their friends why they purchased a song or album on Ping, this activity will also be tweeted to users' Twitter followers ? complete with playable song previews and links to purchase and download music from iTunes.
When users click on a Tweet that's sent via Ping or that contains an iTunes link, they'll see the song or album in Twitter?s details pane, with the ability to listen to song previews from iTunes.
iTunes song previews are available on Twitter.com in the 23 countries where the iTunes Store offers music.
Apple's Ping social network works within Apple's iTunes music program and lets users follow artists and recommend songs to their chosen circle of friends.
