My problem with 'likes' is that it's so context dependent. My favourite colour depends on whether we're taking about paint for the walls, a car, a new jumper or the colour of my finger.
It's the same as for music, my favorite depends on if I'm working, driving, relaxing or wanting to destroy something.
I really don't understand how people can have 'one' favorite and stick to it.
On the excitement front, yeah, I don't get people jumping around with joy unless they're a 6 year old getting birthday cake.... But then I'm British, and we don't do that sort of thing. (Edited for typo twice!)
