This is the soundtrack of the resistance! There's a lot to be pissed off at and we HAVE to stand up against the injustices in our world. We, as members of humanity, must come together and fight for peace and justice! I'd also like to point out I'm a rock and metal guy who despises pretty much all pop, but please give this playlist a listen and maybe you'll understand headbanging and take action!
(I realized this list has a lot of crazy songs, and I thought it would be weird to have some calmer/acoustic songs at the end, so I'll make another list with SOMEWHAT calmer stuff).

Every Rage Against The Machine song EVER (but just to name a few)!
