Me too, I'm searching for an answer. I'm very tired of Vista assuming all my
folders contain music! I'd like a master setting to change all folders. I
never, ever want Album, #, Genre, Rating, etc.
It is a known "feature" or "bug" depending on your view. In short the
design consideration that causes this is Vista trying to help. Most
people instead of thanking the boys of Redmond instead curse them,
because this is just one backward example of Microsoft logic that
mostly frustrates users.
You can have a folder set to show details and have a mixed bag of file
types in it. If you next drop 15 images files into this folder Vista
may "help" by changing the setting to now show thumbnails. Same thing
happens with other file types like dumping in a bunch of songs.
Following explains this issue in more detail and offers a solution. In
true Microsoft fashion since Vista is a over bloated pig with millions
of lines of code fixes have a bad habit on unfixing themselves
depending on what you do later. Since the fix involves tinkering with
the Registry, be sure to set a Restore point first and also make a
backup copy of the Registry.

There is a more involved fix that changes the "bags" value. Somebody
posted it awhile back, I forget who. Whoever did, may see this and
respond.
Oops, I just found it:
