Emms is rather track-centric. But nothing is stopping you from reading
the track information for each track and constructing any additional /
different view of the track information.

emms-playlist-mode.el and emms-streams.el both implement a graphical
interface to a list of tracks.

I don't understand exactly what a "browsing system" is, but I think that
it would be great if you write an emms-browse-mode.el or something to
"scratch your itch".

Emms does not partition tracks along the "album" axis. As I mentioned
above, it is rather track-centric. But supposing that you implement your
idea for a "browse-mode" which is more album and artist aware you should
not have a problem writing the above as an extention of it.

I personally store different albums in different directories, but that
is an artifical seperation and it would be wrong to assume that every
seperate directory is a different album everywhere. So it seems that
creating "album-objects" is the the Right Thing (TM). Good thing that
Lisp is so malleable!

Awesome. Good luck, looking forward to trying out neat stuff from you!
