Shambles, I don`t see why labels should restrict me from exploring different kinds of music. They are just a rough categorization what kind of music is in that bin. Doesn`t say if I like the artist or not.
Nothing - if not myself - prevents me from looking into other bins. And since it is aimed at a general public (not only real music enthusiasts like us) a bit of orientation (debatable as it can be where best to put things) is not so bad.

At home we can use/develop any system we like for keeping our cds.
