So I accidentally brushed the button on my phone that brings up the screen of all the open apps, which then disconnects from the song. I wouldn't be too bothered by it, since it was an accident, but I did it literally at the end of the song. The song was finished... and then I disconnect. Not gonna lie, it was funny, but I really felt like an asshole.
Well, time to change my name and centre in case I run into anyone I was playing with again.
