Update: Well, Google Music is out of the dog-house in my book. Nathan helpfully pointed out that the Music Manager app does downloading as well. It's not perfect, but it will do. Given all the other things that Google Music does do well, I can over look the rough edges.
I'm definitely going to avoid buying music through Google Music in the future (though I still love that they'll hold up to 20,000 of my own tracks for free!). Here's what happened:
Yesterday I saw the deal to get some albums from Google Music for only $2. Being a music fanatic, I jumped right on it & purchased a few albums. Today I decide I'd like to download those tracks to put them on my shiny new ReadyNAS Ultra4+ for safe keeping (no, I don't trust the cloud -- even Google's -- I backup everything, even my Gmail). I hop on my PC, pull up Google Music & quickly find that there is no option to download entire albums or playlists, just individual tracks. Not wanting to waste time clicking multiple times on each track I purchased I jump on my Android (now that just sounds wrong, doesn't it?) pull up the Google Music app & 'pin' my new albums so that they are cached locally. After download completes I plug in USB, & attempt to locate my new tracks. Searching manually doesn't do it so I have to resort to Windows search (did you just get a chill too? why can't MS do search?). It finds my files buried 4 or 5 sub-directories deep but they are not named rationally. Instead they appear to be named using random numbers. No problem, I think, all the info iTunes needs to auto-name my tracks are embedded in the tag, right? WRONG. Neither the tag nor the album art are embedded in the files.
I'm sticking with eMusic. They make it easy to download stuff I ALREADY OWN. See ya, Gmusic. Sure I'll use you when my too-cheap SD card flakes out & I have to stream, but you won't be getting any more $$ from me! (& trust me, when it comes to music, I'm the type of customer you want).
