Free music search engine and player Fizy doesn't do playlists, offer downloads, or fancy looks. What it does have is more than 75 billion MP3s in its index (supposedly), and a really fast search function. For those moments when you're just looking to dig up a certain song and play it for friends or your nagging memory, Fizy is just about perfect. If there's a video to be found on YouTube or other sites, you can pop it open to play alongside the song, or close it down without skipping a beat. It's small, simple, fast, and it covers a lot of MP3s floating around on the web. For a more robust interface to queue up and play the web's MP3s, try Adam's own Mixtape.me. Fizy is free to use, no sign-up required.
