There's a new experimental feature in
Google Play Music Labs: it's called Google Play Music for Chrome and it lets you "control music playback with a new mini player, add your existing music collection, and download free and purchased songs without installing Music Manager."
The Labs feature only works in Chrome and it uses Native Client to bring many of the features of the Music Manager app to the browser (great news for Chrome OS users). It also lets you install a Play Music app that shows a mini player that lets you control your music.
The mini player doesn't work if you close the Play Music tab, so you still have to keep it open.
You can also upload your music directly from Chrome. You can pick your folders or use the iTunes library. By default, Google will continue to monitor your folders and upload new music.
This is the "media file permissions" dialog:
I've picked my Music folder.
You can continue to use Play Music while the files are uploaded. You can check the progress at the bottom of the window, in the left sidebar.
If you don't have a lot of files to upload, you can use drag and drop. Just drag the files the Play Music tab.
When you downloaded multiple files, for example when downloading an album, Google used to create a ZIP archive. Now you can set a download folder and all the files are automatically downloaded to that folder.
