There was a bug introduced, which broke the built in media scanner on N8x0s (metalayer-crawler).

That bug is fixed in the community SSU.

A lot of advanced users disable automatikc running of the scanner and run it manually due to the fact that while running it does use a lot of resources.

Just to comment on the main topic of this thread, I use either mediaplayer or canola, along with the "now playing notifierzf available in extras which shows the track info in a system notification when the player starts playing a new track.
