Finally got my Google MusicBeta invite ...

Setting it up now, with a few dozen tunes.

It seems to want to hook up with Android aps and may not work with my iPad. Upload is very slow, much slower than Amazon's Cloud Player. It does have an auto playlist thingie, that matches music for you automatically, like Pandora. Pulls album art nicely.

Nice interface. Offers shuffle right up front.

More later, when the tunes in the folder are uploaded.
