Lyric discussion by mootinator 

This song clearly positive about the idea of youth, but I don't really understand why people think it's a "youth anthem".

The chorus begins "Tonight, we are young." The implication of the word "tonight" is that, either literally (age-wise) or figuratively (baggage-wise) that is not normally the case.

Now, given that this song was written by an actual person who would have actually been approaching 30 years old after an actual night of drunken carousing, I would be inclined to guess that he was mainly feeling nostalgic about someone from his past who he perceives would have always had his back had one of life's complications not come between them.

But that's just my opinion.
