I'm not an expert here, but my understanding is that South Asian pop music tends to be (primarily) based on non-Western music theories like Hindustani classical music. These theories have different ideas of which emotions are associated with which keys or scales.

Assuming you're not familiar with Hindustani classical music, it's quite possible you're just not picking up on some of it, while many South Asians who grew up on it do understand it (even if they haven't had formal training.)
