It looks like Ping (a music social network from Apple) has a new best friend, as Twitter has just announced that Ping users (not to be confused with Ping.fm or Ping.com) can now connect their accounts with the micro blogging social network.

Starting today Ping, iTunes’ new social network for music, and Twitter are making it even 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. [...]

Once you’ve linked the accounts, 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.

Users who connect their Twitter accounts to Ping will be able to find Twitter friends (or rather people they follow) who also use Ping, which should help make the service easier for new comers to adopt (as very few people enjoy using social networks without their friends).

This partnership is obviously a big win for Apple, as the company previously tried (and failed) to establish a similar relationship with Facebook.

Although its still unclear whether Apple will make a second attempt to pursue a similar relationship with Facebook, we may see the music giant reach out to other social networks in the future (with the exception of Google Me of course).
