Rx Bandits has tons of songs about social issues.
Analog Boy – Lots. It talks about how society slams certain images down our throats, like the perfect woman. At the same time, it talks about how modern society is impacting children.
Sell You Beautiful – I think you can guess what it’s about from the title. Similar to the first half of Analog Boy. The perception of the perfect girl/woman.
Get – Materialism. Living our lives for clothes, drugs, money, etc.
There are lots more, just go through a few of their albums.
Daft Punk’s Prime Time of Your Life also talks about that perfect girl and anorexia. It’s got a very powerful video, as well.
