Songs are not accessible under every category

Hi,

I dont know if this is a bug in xbmc or the system which is accessing xbmc.

I have a fresh installation of xbmc 12.2.
I just have one song album from Dido.

When I try to play this album via my Yamaha AV receiver RX-V475 or my Philips TV 42PFL7685K, I am not able to select this album via Genres.

When I select
Genres/Pop/Dido/Life For Rent/White Flag
I get 'Access error' on the receiver and 'File can not be read or found' on the TV

When I select
Albums/Life For Rent/White Flag
it works

Why? Is this a bug in xbmc or the players ?
I tried it on Linux and MacOS

Regards
Volker
