I love how this song is so massively popular and many (if not most) people don't know what it's really about.
That's the point, if it's catchy it doesn't matter. Plenty of English songs many non-native speakers have no clue about, also French, German, etc
Plenty of songs that are catchy and become big hits are so stupid, you wish
you didn't understand the lyrics.
Everyone knows how to use Google and it only takes a few minutes to get a quick recap of what the song is about.
certainly has more substance than 'Call Me Maybe'.
