My spotify is showing 168.23 GB written and 1.45GB read. Meanwhile, chrome has only written 51.27 GB and read 6.03 GB. This is also on my home computer where I rarely listen to music (usually I listen on my work computer or phone).
On Mac, 13GB Written by Spotify in the last 4 hours as reported by Activity Monitor. I only listened to 10-20 songs.
I've been listening for a few hours now, just checked AM and saw 44GB on disk, but oddly for Network, it has only received 176MB. Where is all the data coming from then?
