Dynamic Music [1.11.2]

[Stroam]

I was wondering the feasibility of changing the music based on triggers such as when player is:

• within a certain x,y, or z range.
• in a particular dimension
• being targeted by any mob
• near a particular mob boss
• in a feature such as an abandoned mineshaft
• near a feature such as a witch hut
• in a particular biome
• near a particular block
• under X hp
• under a "roof"
• riding a horse
• swimming
• it's nightime/daytime

 

I ask this because it's outside of my scope of knowledge which is limited to weapons, crops, and multi-blocks. I'm pretty sure most of it is possible and mostly concerned about being targeted and proximity to block, mob, structure, and dungeon but I thought I'd ask before spending few weeks trying to get it to work.
