^ Slavo, if you get Spotify premium, it's 320kbps
320kbps should be indiscernible from flac unless you have super-human hearing
I always recommend getting Google Play Music/Youtube Premium for $10 a month instead of Spotify though. It's 2 services for the price of one - PLUS it allows you to upload local music files and stream 'em anywhere which I find especially neat
Or there's always Tidal for 'audiophile streaming', but...
