The speculation last week about Google’s music search plans was pretty much on the money. Announced officially last night, the company’s new search features will provide streaming previews when people search for song titles or artists – or even specific lyrics. iLike and Lala are the two main partners as previously reported, although the iLike element will be branded as MySpace. However, Pandora, Imeem and Rhapsody are also on board, providing links to “music related to your queries as well” – a recommendation element, in other words. The new feature is only available in the US for now. So how does Google decide which partner to serve links up for each query? A virtual coin toss, apparently.
