It's not very IMS for me to enthusiastically recommend an act as...earnest as Flobots, but I really like the single:

so I bought the album on iTunes, and I have to say I'm very pleased with it. Another highlight, in my mind, is "Same Thing" (not a video):

We say yes to grassroots organization

No to neo-liberal globalization

Bring the troops back to the USA

and shut down Guantanamo Bay

Who let 'em overthrow Jacobo Arbenz?

Who let 'em overthrow Mohammed Mosaddeq?

Who let 'em assassinate Salvador Allende?

I didn't let them but they did it anyway

Earnest as hell.
