The freezing could be a heating issue. My 2015 MBP was doing the same, and the fans seemed to always be in high gear. I took the back plate off, cleaned the fans, and it performs like new again.
I too have been having this issue as of late on my mid 2015.
Me too, mbpro 2013 or 2015 I'm not sure. Music or video keeps playing, input freezes. Very rare, but not rare enough to not notice.
I've seen it on my Mac mini a couple of times. I thought it might have been a bluetooth issue as both the keyboard and mouse were unresponsive but perhaps there is something else going on.
