Last week, Google announced a new taste of rich snippets, this time for music pages. At that time, I couldn't see the new snippets, but now they ought to be obtainable for everyone.
"With this new feature, site owners can mark up their pages using the newly shaped music markup spec on schema.org, and search results for that site may start displaying song information in the snatch so that users know that there are songs or samples there for them to listen to. Several early partners have implemented the music markup on their sites, counting MySpace, Rhapsody and Reverb Nation," explained Google.
The new rich snippets comprise links to music pages that could be establish by visiting the search result, but it's faster to bypass the search result and start to play a song. It's important to talk about that the songs aren't played on Google's results pages, so you still need to go to a different page. You'll only see the music rich snippets when your inquiry includes the name of an artist, a song or an album.
Google also shows rich snippets for events, profile pages, recipes, videos, reviews and products. "With rich snippets, webmasters with sites containing structured content—such as review sites or business listings—can label their satisfied to make it clear that each labeled piece of text represents a certain type of data: for example, a restaurant name, an address, or a rating."
At some point, Google will make structured data searchable and it will be a lot easier to purify results. Recipe search previously lets you do that and it's pretty useful.
