Looks like Google is planning on releasing a cloud music player soon and it's already in Beta. I requested an invitiation to use the Beta and will hopefully be able to try it out soon. I love the idea of having my full library anywhere I go and it looks like a great interface.

Google Music, the streaming music answer to Amazon, MOG and Rdio, is here (in beta form). You can access music in the cloud and stream to devices. But unlike MOG and Rdio, you can only play what you upload.
Google Music is less streaming music service, and more storage locker. You upload your tracks using a desktop client for Windows and Mac, and you can manage those tracks via a simple, clean UI on your computer, smartphone or tablet. Sure, you don't get access to millions of tracks, but if you already have a good library, you get access to the music you want. Here's a look at some of its features:
• Library Upload: With the Music Manager app, you can upload your iTunes or Windows Media Player libraries with one click. You can also upload by file or folder.
• Offline Listening: It's a pretty standard feature, but Google's gives this feature a neat twist by automatically caching songs you've recently listened to. I'd also love to see them do this for most listened songs. And of course, you can also cache specific songs you select.
• Seamlessness: Any change you make to your Google Music library on one device is automatically pushed to other devices.
• Playlists: Once you upload your tracks to the Google Music cloud, you can play around with it just like it was in a music app. That means playlists which automatically sync across all your connected devices. They also have a smart playlist feature called instant mix, which will automatically build a list for you based on one song. It's like iTunes' genius or Pandora's recommendation bot. Google says that they have servers actually listening to the songs to make their playlist selection.
Google Music is currently in beta, but you can request to get earlt access right here (and if selected, you can upload 20,000 tracks for free! FREEEEEEEEEE!)
