Along with the new mobile web version of Google Music, today Google is announcing a new discovery service that introduces users to music they may like based on what they already listen to.  Watch out Pandora!

Announcing Magnifier, our new music discovery site

When we launched Music Beta four months ago, we wanted to help users fall in love with their music again by removing the hassles of digital music management. We’re now taking that idea one step further with the launch of Magnifier, Music Beta’s new music discovery site.

Each and every day, our team of music experts will highlight new, free music on Magnifier. Sometimes it will be songs you haven’t heard of by artists you have. Sometimes it will be new artists we think deserve more attention. And sometimes there will be video interviews and live performances.

But you can always count on the following:

• You can add any or all of the songs to your Music Beta library instantly
• You can do this for free
• The artist is being featured because someone on our team thinks they’re pretty great
