Twitter has just announced that that they've integrated with Apple's social music network, Ping to make it easy for users of both services to share music.

On Ping you can easily link to your Twitter account to instantly find Ping users among the people you already follow on Twitter.

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.

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.

This follows Apple's inability to come terms with Facebook over social integration.

The real question is, will Twitter integration make Ping more relevant? Is it enough to get you to use Ping more? Or to use it at all if you haven't already? Or would Facebook still be a better option?
