[emms-help] Handle missing artist info in emms-info-track-description

[Andreas Hoenen]

Hi,

I'd kindly suggest to let emms-info-track-description handle the case of
missing artist, but existing title information by displaying the title
instead of falling back to emms-track-simple-description.

Rationale:

There are streams outside (e.g. [1]) that seem to put all of the track
information into the title field instead of properly distributing it
among the appropriate fields.  For these streams something like

Currently playing: Cryosleep - Zero Beat Guaranteed: Steve Roach - 08 - Altus

is more informative than the current output:

Currently playing: Cryosleep - Zero Beat Guaranteed: url: 
http://207.200.96.225:8022/

BTW, as an inveterate Emacs user I really appreciate the EMMS way of listening
music — thanks for your work.

(System information: using Debian package emms 3.0-5)

[1] ("Bluemars Cryosleep" "http://207.200.96.225:8022/listen.pls"; 1 streamlist)

Thanks for considering, Andreas
