Hi Felix,

IMO, the previous code was really hackish and misleading. They was no real chars comparison here, just the comparison of the pointers to the static allocated memory. It worked because the compiler was smart enough to allocate only one memory place for each media type string, but I'm not sure if thats guaranteed by every compiler.

So, I wanted to do it more clear, and I don't wanted to use c-string comparison in an Obj-C-plugin, so I thought that NSString would be suitable. Actually, I planned to use int or something like that, but for the second patch I needed an id object. And now, its consistent with the way the column types are declared in playlist.h.

Best regards,
