What do you typically listen to while playing Minecraft?
I myself like to listen to ambient stuff like the actual songs by C418. He has some other albums that are great too.

Lately I have also been really into the SimCity ost

I turn on Spotify and listen to my playlist

I don't normally have music on other than the random music that comes on. Because I am normally chatting with others on team speak. But I leave the ambient stuff on because it often plays at a good time when I've just achieved something, it's quite cinematic
