I've read that Google Music deals in 320kbps MP3. No idea if it converts/replaces music you upload to the service to that format/resolution.
Google does convert your music to MP3 when you upload it. I have my whole collection there for streaming on a phone but I also have the whole thing backed up on MS Onedrive as full FLAC files.
Thanks for the musings, @RickB & @Robert Wortman . Re: Google uploading and re-coding it to 320 Kbps MP3. That makes sense. It can play on almost any player (unlike ALAC & FLAC). Other than the odd pop & ping (from flaky internet-and-or WiFi), it sounds bourbon-smooth when I stream it off my Google account. It's good enough for SCUBA-ravaged ears. While my music's backed up on local/off-site external drives, @Robert Wortman 's suggestion makes sense.
It never hurts to have ones' music backup in >1 place, eh.
