I followed a bunch of Balkan artists, and am now constantly getting Balkan songs recommended to me through Flow. ALL of these artists have at most 1-2 songs each that I like out of X (ex: 125) amount of songs they have uploaded. I am constantly finding myself clicking on the button to not recommend a specific song. I spend more time banning songs, than I do listening to songs.
In hindsight, I do regret following a bunch of Balkan artists. I am no longer getting any US songs on Flow.
