Google is currently showing off some amazing Android Marketplace improvements right now. You can now browse the Android Market from your desktop and send apps and music directly to your device over the internet without having to tether over USB (yet another shot at Apple there). Yep, Android Marketplace will be selling music soon.
What has us really pumped, however, is that they're currently demoing the ability to stream your own music (provided it isn't locked under DRM) from your desktop to your Android phone.
We're looking forward to Froyo more and more.
