Underrated Indian music?

I'm looking some refreshing Indian music. Could be singles or from movies... any language from across the country. I am a carnatic musician so listen to a lot of carnatic or fusion pieces. Occasionally the south Indian in me blasts kuththu. I am a sucker for folk music. Learnt quite a bit from karnataka..obviously have expored a bit of rajasthani. But.. i wanna dive deep. (And obviously also listen to mainstream cinema music, but i havnt enjoyed much of it for almost a decade now. In any language tbh). Please share some gems. I'm open. Dont stick just to what I mentioned. Ps: the one thing I may not enjoy much is instrumental music, but a select few have made me feel otherwise. So... would love to hear suggestions here too.
