If I recall correctly, there are a fixed amount of BROs distributed every hour to all listeners. The more people listen, the smaller the share. I think it is currently 4 BRO per hour according to OP first post? But on reality, I find if I stream maybe the whole day or 18 hours more or less, I get maybe 0.2-0.3 BRO. But it's free anyway I leave a tab open.
im getting 0.6-0.7 bro per day if i listen to music
That's about right then, if you listen 24 hours? I get around half of what you do from 12-18 hours. But it stops on its own every few hours, so I guess I lose hours if I'm not paying attention when the music stops.
