The permissibility of music and dancing

I went to a show.
It was my friend Anders' show, so it was a couple stam songs and lots of Jewy stuff.
But I'm not sure if it was right.
I have questions:
When is it mutar to dance?
What types of music are "ok"?
What are the dividing lines?
What are the sources?
I'm sure that the answer is "machloches" as usual but I've never looked into it independently. I aim to find some answers by the end of the day, brb!
