Was my Mother rude in this situation?

I was sat on the couch watching a symphony orchestra by (I think it was a Johann Sebastan Bachh concerto) but not him conducting it obviously, when my mother walks out of the room saying Oh my god how can you listen to this sh** and made a drink, the volume wasn't high and it isn't irritating the music was very soothing, i just want to know the remark she made towards the music was it insulting or not.
