However, even then, this slight difference is well papered-over by just including the music director in the list of artists who made a song.
Indian classical music, however, has a wholly separate and more intricate form of organization. You'd at least need raga and the properties of the raga (like the dominant rasa & associated time of day), along with the various singers and instrumentalists in the ensemble and their instruments. It would be great to search for "morning"-raga-based Carnatic vocal concerts with the lead singer being Sudha Ragunathan.

That's the only way your voice will get heard.
It's interesting, what even is classical music? I bet there's music that crosses boundaries, like jazz-classical or pop-classical. Are those subgenres on the app?
