I see no reason not to display network streams in the browser, and to
associate images with them to boot.

The artwork would have to be mostly user-supplied, and we need to come
up with a way of pairing an image with a specific stream.

Perhaps each stream can generate a short hash which we can turn into a
filename ("DK2RSK3DEU.png"). Then the browser could check for the
existence of "~/.emacs.d/emms/stream_images/DK2RSK3DEU.png" and cache
that.

If we can get people like Soma.FM to give us copies of their per-stream
artwork under a freedom-respecting license, then we could ask the FSF
(as copyright holder of Emms) for permission to ship that artwork along
with Emms (without Soma.FM assigning copyright). Otherwise, we would
provide instructions for the user to do so independently.

A native Emms playlist has two parts: a header string as defined by
`emms-source-playlist-native-header-line', followed by writing out the
sexp representation of the tracks.

So if you where to look at how a track is represented by invoking
(emms-playlist-track-at (point)) over a playlist track, you'll find that
same sexp written out if you save the playlist in native format to a
file.

Thank you for writing in to improve Emms.
