I got folder called "l. v beethoven - string quartets vol.5". Amarok can't read tags from files in that folder.
when i change it to "l. v beethoven  string quartets vol.5" he read tangs wrong!
Song are tagged Artist:"Beethoven, Ludvig Van" and amarok reads "Ludvig Van Beethoven". How's that even possible?

So i copied this folder to different location. Now amarok Read "Beethoven".

So, depending on location and folder name, file tagged as "Beethoven, Ludvig Van" amarok reads like non-tagged file, "Ludvig Van Beethoven" or "Beethoven".

(amarok 2.0.1)
