This is only for those of us with dubious ethics.
Ah! Good, you're still here.
If you've got an Android phone and a Google All Access music account here's how to get free music. Free as in it's yours to keep, won't go away and is at 320k MP3.
On your Android phone go to the Play store and download Cloud Music Importer (CMI). This app is originally designed to put name/artist/album to the tracks you elect to 'keep on device' in Google Music so you can play them in your player of choice instead of the crappy and hard to use stock music player - but it has a more useful role in life. Note - I'm not talking about your own music you've previously uploaded - that doesn't figure into the equation at all. Okay, the app's downloaded and you have 50 free track downloads before you have to pay the $4 for the pro version. Now for the 'free' bit. Go into Google All Access and add stuff to your "My Library". Go back into CMI and sync it. You'll see the added tracks in the list of available files. Just hit 'Save to disk' and they're yours. When your free 50 is up pay for the darned app! It's worth it.
The app does seem to be living on the edge and subject to Google's unannounced changes, probably because it's using unpublished APIs. Still worth it though.
