1) What are some examples of music that is not played in gatherings of vice and evil?

2) Is there a difference of opinion among shi’a marjas on the topic of music or is there a consensus?

1- That varies from one society to another. In your society, if there is a type or music that is generally not played in concerts or entertainment gatherings (like some types of classical music or therapeutic music or war music) then it would be permissible.

2- There is a difference of opinion. Some understand that all/most types of music are haram. Some believe only if it’s the type that’s suitable to entertainment gatherings then it’s haram.
