i have been tryin to figure this out for a while now, how can i get ppl that search for a song to have it show up

just putting songs in the folder DOESNT work

im a producer, so lets say i wanna put a song i produced on there for ppl to search and be able to download it, is it somethin to do with ID3 tags or what because i have tried time and time again to just drop the tracks in the folder and nobody can ever look em up

little help please??
