Metadata matters. A listing that simply gives title and artist is useful for quick retrieval but impoverishes discovery. Imagine an entry for “Tere Bina” that also tags year, film, lyricist, musical scale (raag), and socio-cultural notes — for instance, that it marked a songwriter’s political turn or used an uncommon instrument like the sarod in a pop arrangement. Those tags transform an A-to-Z site into a map where songs connect by theme, era, vocal style, or social function: wedding songs, protest anthems, lullabies, or songs that captured migration narratives. Example: tagging “Chaiyya Chaiyya” not only under S for Sukhwinder Singh or A for A.R. Rahman, but also under choreography, multilingualism, and train imagery would expose its cultural reach beyond a single letter.
