I think it should go like this: 聽了整個精神都來了. 讚. So the last char is "Like"

Here, 讚=awesome , very good.

When I heard about this, I feel so excited I would use "exciting' to explain '精神都來了" 讚 = thumb up = like / awesome and there should be a comma in the sentence as below. it would be more easier for you to understand this sentence. 聽了整個精神都來了, 讚! (When I heard about this, I feel so excited! awesome!)

In my opinion, it's like 'awesome' in this sentence. I have high energy after listening to the song , awesome/great/wonderful! Anyway, it is an adjective for "聽了整個精神都來了" Sometimes we use it as an ironic word as well and it depends on speaker's attitude or contexts.
