Although we prefer AppFinder for searching the Marketplace for new wares, it's nice to know Microsoft is still tweaking things a lil' bit on their end. Evidently, in the last 24hrs, Microsoft has added keyword-search to the Marketplace, making it very slightly easier to find apps based on topic as opposed to just searching by title alone.

As you can see in the image to the left, searching for Google brings up a few apps with Google not in the title, which is probably a welcome feature for developers too. But as you can also see, music still pops up to confuse your results, which leads us back to AppFinder...
