"I can’t kauf, when I'm blue on Monday" by Supershirt (feat. Kylie Minogue) is a song that speaks to the idea of consumerism and how it negatively affects our lives. The chorus urges us to "Kauf weniger ein" which means "buy less" in German. The song suggests that we should avoid the impulse to constantly consume and shop, as it leads to a cycle of needing to work more to afford more things, leaving us with less time for ourselves.

The first verse paints a picture of someone who is constantly buying things they don't need and is left with no money. The second verse calls for a rebellion against our consumerist culture, suggesting that people should strip down and embrace simplicity instead of chasing after material possessions.

Overall, the song is a call to take a step back from societal pressures and to focus on simple pleasures in life, like spending time with ourselves and our loved ones. It encourages listeners to embrace balance and to find happiness in the small things, rather than constantly chasing after material possessions.
