When I play games with friends, I often use discord for voice communication. We use the built-in bots that are really glitchy and often cause latency in-game. The bot simply looks up the song on youtube and plays the top result, which could be occasionally the wrong song. I really wish that Spotify will add support for discord. And by using the system for parties, we can have friends queue up songs and DJ without the laggy and annoying bots.
