verb + のさ = ?
In two songs, I heard "verb + のさ". (At least I /think/ のさ is supposed to be used with verbs?) I don't understand what のさ is; it's not in my dictionary.

I can mostly understand the sentences besides that. Both verbs have 出す and のさ, too.

1. 「LASTICA」 by カラス:
さよならここから抜け出すのさ月夜へ
Goodbye, I’m sneaking out of here into the moonlit night

2. 「落とし穴の底はこんな世界」 by 摩天楼オペラ:
生み出すのさ　この世界から　もっと憎しみを
More hatred is born from this world

Answer

it's a 'sentence-final particle',の+さ
speaking in a friendly tone
they have no great significance
we use them simply to arrange our tone

Answer

Hahaha, it is too difficult to explain by my English.
I probably think that "verb+のさ" is similar to "verb+んだ" 
抜け出すのさ = 抜け出すんだ
生み出すのさ = 生み出すんだ

2. Let's create more hatred in this world!

Uuun....I can't translate it well,sorry.
