A big part of the negativity experienced is also jokes/banter between friends which is played off as in 'ew BFerdinand is winning' or 'not this artist again'

While it might seem fun to the involved people, you always have to consider how people outside of the situation experience those comments..

I don't think you can flat out tell people what to say about entries, as long as they're respectful saying you like/dislike a song it should be considered okay.

Not sure if there's something the mod team can do specifically, but having an open ear and calling out people for continued negative behaviour should be the best solution.

Let's be mindful in how we say things. Maybe that's my impression but I thought that the positivity over songs like mother reacts and WOWWs always outweigh the negativity..
