So The Lord of The rings Online is having music festivals all summer long. They're great fun and they would fit this game even more!
We could have bands perform at our impalongs, people dancing (animate that emote please :P) and cheering along.
It gives players a new thing to do and crafters new instruments to make.
It could even be a new subskill for carpentry, making and tuning instruments.
I know that it would be a lot of work to implement something like this but I think that it would be worth it and with the new update schedule it should be possible I suppose.
We could use more fun-features in this game and this would be one.
