Twitter said that starting today Apple’s iTunes’ new social network for music Ping and Twitter are making it easier for people to share music discoveries with their friends by putting Ping activity, song previews and links to purchase and download music from the iTunes Store right in their Tweets on Twitter.com.
How does it work?
On Ping you can link your Twitter account — once you’ve linked accounts — now, whenever you Post, Like, Review, or tell your friends why you purchased a song or album on Ping, this activity will also be tweeted to your Twitter followers — complete with playable song previews and links to purchase and download music from iTunes.
When you click on a Tweet that’s sent via Ping or that contains an iTunes link, you’ll see the song or album in Twitter’s details pane, with the ability to listen to song previews from iTunes, making the experience even richer.
iTunes song previews are available on Twitter.com in the 23 countries where the iTunes Store offers music.
