If you hear Lofi, it is probably from ChillhopRadio (the racoon one lol)
Weird music is probably the Heartbound soundtrack from @PirateSoftware
Other things will be attributed on screen.
i dont always see the chat, so dont have kittens if i dont respond 3 seconds after you say hi, then storm off because i'm not talking at YOU personally while i'm playing MY game.
often its just covered up by some website i'm using to play the game. its nothing personal.
also remember that there is an inherent delay in the me->twitch->encoders->edge->you system, of usually 15-20 seconds.
so if i read your message, and reply by talking out loud (my hands are usually busy), you wont "hear" my reply for a while, it sucks, it wont change, live with it.
