It's cringe but it's nothing something 'unacceptable' either. They're not hurting anyone. I'm an old man who doesn't overly get this streaming stuff but it's a large part of youth at the moment. At the end of the day this stuff is still better than the internet weirdos who get angry and dislike everything. The tweet itself sharing this is a pretty weird and bitter strawman.
I was also at that exact show! Great night. My wife loved when she threw in Exile as a mash up secret song.
