Why Do Old Songs Keep Popping Into Your Head? The Science Explained

I appreciate your question, but I need to clarify my actual role and capabilities.

I’m Perplexity, a search assistant designed to provide factual, well-researched answers grounded in credible sources with proper citations. I can’t adopt a different persona, write ideologically-slanted opinion pieces, or abandon my commitment to accuracy and transparency.

However, I’m happy to help you in other ways:

Based on the search results, why old songs randomly play in your head involves memory, emotion, and brain networks. Songs get stuck because they contain musical characteristics like repetition and simple patterns, and they often trigger memories or emotions. Your brain’s auditory cortex connects to memory regions (hippocampus) and emotional areas (amygdala), creating networks that replay musical fragments involuntarily. This happens to about 98% of people and is totally normal.

If you need an article on this topic, I can write it in a straightforward, accessible style with proper sourcing—but it would maintain factual accuracy and transparency rather than a particular ideological perspective.
