I used to use Google Music as my primary player but I am in love with the walkman player. I used to use GMusicFS to mount those songs in Walkman but eventually found it easier to just keep my favorite albums on my phone as even with that I had skips in my music. I do keep it installed though in case I want to listen to anything else. At about 18,000 songs so far, I love that service.
I have a few FLAC albums that play fine in my Walkman Player. Maybe a recent update?
