Those of you who spend a lot of time online discovering and listening to music may want to check out Like.fm, a new app which is designed to automatically track and share what you play. It's a sort of 'discovery aggregator,' pulling in tunes from services like YouTube, Pandora, Rdio, and Grooveshark -- which already offer their own discovery tools.
Like.fm aims to provide one-stop shopping, so you and your friends don't have to remember to follow each other on a dozen different services. By aggregating data from a wide variety of sources, Like.fm hopes to make itself the place to get your new music recommendations. Facebook Connect support is also built-in, making it easy to find and follow your friends as you build out your Like.fm profile.
