I think the album name "Wide Awake!" (in addition to the eponymous song on the record) is a play on the term "woke." As in they're conscious/aware of sociopolitical issues, particularly in the US.
'Violence' is a critique of violence in the United States, and speaks to how increasingly numb we are becoming to it: 'Savage is my name because Savage is how I feel When the radio wakes me up with the words "suspected gunman" ' is an especially poignant lyric today, 5 years later. Every time I see a new report of a school shooting I think of this song.
'Before the Water Gets Too High' is pretty self-explanatory based on the title as well, the song describes how we prioritize profit over environmental protection in a capitalist society, but the money we make won't matter once the earth is fucked and Wall Street is underwater. And also touches on wealth disparity, but that too will be irrelevant eventually "when the rich become refugees".
'Normalization' speaks about the normalization of the toxic culture of our political discourse. Which again, is very relevant still and seems to have only gotten worse since 2018.
The final song 'Tenderness' is forward-looking and ends the record on a lighter note, and to me is about how the new generation can enact change, and about the hope that the world can be more "tender' and kind.
Not all the tracks could be considered 'protest' songs, Freebird II and Death Will Bring Change (which is actually about how one of the band members lost his sister in a car accident, and how that affected him) are a lot more introspective rather than a commentary on society.
But overall, and also the fact that they chose to name it Wide Awake, the tone of the record is very much a protest of sorts to various issues we face in the US and across the world.
