Usually international fans think 'gp friendly' songs are bright, often cute concepts, or ballads, songs that are easy to sing a long to with a beat that isn't "noisy".
When Aespa's Next Level was released it was described it as experimental, disjointed (some said it felt like two songs put together), but it has become a stable high charting hit in Korea! Not your typical gp friendly hit.
So what do you consider as 'gp friendly' music?
