Apple and Twitter have teamed up to allow users of Apple’s Ping social networking service to share items between iTunes and your Twitter feed.

[ad#Google Adsense 300×250 in story]In a blog post on Thursday, Twitter said your Ping activity could be automatically tweeted on your feed. That includes song previews and links to purchase and download music from the iTunes Store.

For instance, I just “Liked” Ozzy Osbourne’s “Crazy Train” on iTunes and it was posted to my Twitter followers. If you use the Twitter website to view the tweet, it can be expanded to show the the preview and link to iTunes.

When you login to Ping and link your Twitter account, it will automatically suggest people for you to follow on based on your Twitter follows. Quite handy really — I started following several new people on Ping with the integration.
