ok.. uris seems good solution..
btw, i found genre has no unique identifier (or uri).. so would tracker have
the flexibity to create new or update table for genre which will store its
own unique identifier?

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...
