The views are ordered by whatever they are specified as in MC.
If you use the default views, then yes, these two views are ordered alphabetically by default.
There is nothing to prevent you from changing the ordering of the views in MC though. If you change the album view to sort from Z-A, it will break the index bar that expects an A-Z ordering.
The list and imagelist view modes are different. They are actually ordered and grouped manually in JRemote. This was done in order to group the results into sections with headers. The thumbnail view does not have those sections.
If you look at the "recent" view it displays correctly in thumbail view mode, but the list and imagelist modes do not. They are grouped alphabetically even though the original list is ordered by date.
The previous implementation of the thumbnail view would work correctly if the list was sorted alphabetically, this is the solution I am reverting back to.
The current order/grouping in JRemote is artificial and subject to break depending on what view you are using.
In the future I plan to come up with a better sorting, but it will require some changes to the web service.
