Yes, VLC also should not provide that (such a music DB) (I think). But when it provides some API, a plugin/module, or even another external app could provide that logic, i.e. the music DB itself, also the UI to search in the DB, and then also the logic to add something from this DB to the VLC playlist. It would be nice if there is an API such that VLC can be extended to make that possible. But yes, I definitely think that it should be a separate and optional module/plugin/app/script.
