here's how i define a mantra song: it covers a specific emotional experience or mindset shift and offers words to help you better understand yourself. while the entire song may be much longer than what you would actually use as a mantra, it contains at least one line that stands on its own to remind you of the entirety of the rest of the concept so it's like a shortcut for your brain. depending on the situation i'll often sing myself a whole song, but sometimes a snippet is all you need to quick
