No it does, but it won't group with the granularity you are looking for. There are a couple hundred "group by" fields, you may need to either look through them and see if there are any that are specific to a video or music type file and group by that or if you can find a program that can edit those properties you could use a blank one such as Comment and for example tag all your videos files as "Video", the different types of music files as "Music" then you could group by the comment field and achieve what your looking for.
