That's not completely correct. Each artist, album, playlist has its own URI (based on uuid in some cases). "Song" is nmm:MusicPiece and share uri with the DataObject (the media file in your terminology)
but i found tracker is generating

As you say, it is an *internal* ID. You can access it with the tracker:id function, but it is not recommended at all. URIs are the identifiers of the resources.
Indeed, the uris has quite more chances to be unique between dbs...
