Can you help me explain this sentence いつも笑っていたいよね word by word？
What I have known:
both よ and ね are mood words. But when they come up together ?
いつも means always.
笑 means laugh
ていたい I hope...？ I simply know this pattern が欲しい
I'd appreciate it if I could get some examples.
What's more, this sentence derives from a song sung by Ohguro Maki where there is a similar sentence
辉いていたいよね

Answer

In my understanding, 「よ」 is simply mood word. 
So, for example "食べたい" and "食べたいよ" are basically the same meaning, "I wanna eat".

But 「ね」 sometimes includes asking for opinions or getting others consent. 
...を食べたい　I wanna eat ...
...を食べたいね　I wanna eat ... (+ How about you? / do you wanna too?).

So, when you wanna get others consent, you can put 「ね」 in the end of the sentence.

それができるのは今しかないよね　This is the only time when I can do it (+ How do you think? / do you think so?).

この部屋暗いよね？　Is this room dark? (+How do you think? / do you think so?).

I hope it can help you learn Japanese :)
