Thanks for your reply. I'll see in how far I'm able to find the ogg files in 433GB worth of music. 

Any idea why the recognized parts of my library show up in a seemingly random order (yet always in that same order)? It seems that the Tangara sorts it by another factor, but I have no idea which one it could be. Justin Timberlake isn't the first artist I put in my iTunes library, nor the smallest file, nor the largest... ?..
