AFAIK there are two API call to get the artwork for the currently playing
track.

One is a songinfo query, and use the tag 'c' to get the coverid value, and
use the url http://<server>:<port>/music/<coverid>/cover.jpg .

Other is http://<server>:<port>/music/current/cover.jpg?player=<playerid> .

It seems that the first approach does not work for Spotty tracks. It always
returns the generic 'radio' (antenna) cover. LMS web client and other
clients show the right cover in this case, so apparently it is just the API
call.

The seconds approach seems to work for all tracks.

Since I'm only interested in the current track artwork, are there any
drawbacks to not use the second approach only?
