Readding file without having to rescan all music library

[Makenai]

Sometimes I forget to mount my music library while playing music using Spotify. It will play all Spotify streamed music, but when it goes to a song in playlist which is in my own music library it will fail to play it and skip to the next song, which is definitely normal behaviour. Later after I mount the partition my music is in, most of my music library files which were in playlist willshow that the "file could not be found", even though they are there... Is it possible to force a rescan of specific file, without having to import all music library again?

Here's what it looks like.
